Cable Management Tips For Computers

Computers are getting more advanced, especially wireless technology and connectivity, but it will probably be some time until a complete wireless office is a reality. Until then, computer work areas are going to need cable management for optimum safety and visual acceptance.

Cable management includes clamping, labeling and routing. There are various products to bundle h07rn f cables together:

o Spiral Wrapping – This can be wrapped around cables without disconnecting them. It is flexible so routing of the bundle is easy.

o FLEXO WRAP – A hook and loop expandable sleeve designed for quick and easy bundling and protection of wire, cable

o Cable Ties – These are nylon ties available in various lengths and colors. They can just bundle a group of cables or secure to another item.

o Velcro? Ties – These are similar to twin and earth cable ties, but using Velcro?. Some have a mounting hole to secure to a something solid.

o Cable Management Box – Made from plastic and holds up to seven cables. About 15″ in length and 4″ wide with self-adhesive sticker for mounting.

o Clips & Clamps – There are various individual clips and clamps to mount cables to a stationary object.

To start cable management, group cables generally going to the same destination. Don’t bundle power cables with data 2/0 welding cable if the run is more than a few feet. The electrical field from a power cable can sometime interfere with data signals (USB, network, printers, etc)

Next, secure the cables together with tie or wrap. Pay attention to routing since bundling a group of cables together sometime requires a cable to be longer than it actually is.

If there is a surge protector, position it for easy routing of welding cable price list. Power adapter units sometime take two spaces when plugging into a power strip. Use a universal power cord adapter to alleviate the problem. This is a one foot power cord extension that allows the power adapter to be located about a foot from the power strip allowing use of all the receptacles.

After implementing cable management, all the cables will be more secure and look a lot better!

How to Install Solar Panels: Wiring in Parallel VS Wiring in Series

Planning to build an array of solar panels? Before you start soldering solar cells you need to determine how many panels you will need in order to meet your energy output goals. Of course, in order to do that, you’ll need to have an understanding of how to house electrical wiring your panels together. This article will explain the difference between parallel solar panel installations and series solar panel installations, and it will give advice as to which you should use.

Wiring Solar Panels in Parallel

Imagine that you are looking at three solar panels lying next to each other on the ground. On the top of each panel is a positive terminal. On the bottom of each panel is a negative terminal. You are going to wire these panels together using the terminals. You have two options. Option one is to run wires along the top, connecting each positive terminal together and to run wires along the bottom, connecting each negative terminal together. This is a parallel solar installation. What happens when you electrical wire size your panels in this fashion?

When you wire your solar panels in parallel, the total voltage output remains the same as it is in a single panel. The amperage output becomes the sum of the output of each panel. For example, say each of your panels produces 12 volts and 3.5 amps. The total output of your panels, when wired in parallel, would be 12 volts and 10.5 amps. What would your total output be if you had six panels instead of three? Your voltage output would remain the same, 12 volts, but your amperage would increase to 21.

Wiring Solar Panels in Series

Now look back at those three unwired solar panels lying next to each other on the ground. This time we are going to wire them in series. Instead of wiring the positive terminal of one panel to the positive terminal of the panel next to it, we are going to power cable manufacturers the positive terminal of one panel to the negative terminal of the panel next to it. Do this for each panel, and your array will be wired in series. What is the result of this?

When you wire your solar panels in series, the amperage remains the same, and the total voltage output becomes the sum of the voltage output of each panel. Using the same three 12 volt, 3.5 amp panels as above, we can see the difference. Wired in series, they now produce 36 volts at 3.5 amps. What if we hook up our three other panels? Correct. Our amperage remains at 3.5 and our voltage output jumps to 72.

When to Use Each Respective Wiring Style

Which wiring style should you use? Well, that depends on the system that you want to charge. Let’s say, for example, that you want to use solar power to charge up your RV while camping. An RV, as you know, uses a 12-volt system; therefore, you would want your solar panel system outputting 12 volts. So, if you have two solar panels and each produces 12 volts at 3.5 amps, you would want to wire them in parallel, which would keep the volts at 12 and increase the amperage to 7.0. If, on the other hand, you have two solar panels and each produces 6 volts at 3.5 amps, you would want to armored cable them in series, which would increase the volts to 12 while keeping the amps at 3.5.

You may be wondering what the effects are, in regards to total power output, of wiring panels up one way or the other. The answer is that there are no effects at all. Total power is measured in watts. To figure out the total wattage of your charging system, simply multiply your amps times your volts. For example, say you have one system producing 12 volts at 10 amps and another producing 120 volts at 1 amp. Which produces more power? Neither.

12 volts X 10 amps = 120 watts

120 volts X 1 amp = 120 watts

For simple reference in regards to the difference between parallel and series wiring, just remember that parallel wiring = more amps, and series wiring = more volts. With a sound understanding of the differences between parallel and series solar installations, you are now ready to design and build your own solar panel system.

Installing a Solar Panel Aboard Your Boat

Following a recent five-day trip aboard our trawler where we had to frequently start up the genset to provide electricity to the 115 volt AC freezer to maintain temperatures, I began to mull over options. We put in an excess of ninety hours on the vessel generator in only five days; time for another oil change! I put in an inverter soon thereafter and that improved the run time for the generator drastically, but there was still work to be completed. I nonetheless needed to keep the 1 gauge battery cable fully charged to operate the inverter. Then it occurred to me, why not explore solar panels for use aboard our yacht. Solar panels have been successfully utilized since the mid 1950s, originally utilized in manned space exploration. They have been dropping in cost since roughly 2004 when their popularity really went up. And now with the Green pressure going on, solar panels are as accepted as ever. So I commenced to delve into them and find out how to purchase and mount one; I was in for a big surprise. You can come across many retail vendors over the internet that will sell you a solar panel but nowhere could I locate a detailed description of how to determine what to buy and how to install it; much less on board a yacht. So this piece was written as I made my way through the progression; therefore is a truly a learn-as-you-go article.

What Exactly is a Solar Panel and How Do They Work?

Solar panels are basically any panel that makes use of the sun’s thermal energy to create electricity. A solar panel can be described as a photovoltaic panel, the name used in the business, for panels intended to create electrical energy from the emission of the sun. Despite the group of solar panel being discussed, nearly all solar panels are flat. This is because the surface of the solar panel cable 4mm needs to be at a 90 degree incline from the sun’s rays for the best angle to soak up the sun’s rays. Solar panels are able to absorb energy from the sun through a collection of solar cells on their surface. Very similar to how a plant is able to take in energy from the sun for photosynthesis, solar cells function in a comparable way. As the sun’s rays hit the solar cells on a photovoltaic panel, the energy is transferred to a silicon semiconductor. The power is then changed into (dc) direct current electrical energy and then passed through connecting wires to ultimately enter a storage battery.

Kinds of Solar Panels

Types of panels most normally used in yachting uses have either multicrystalline or amorphous thin-film cells. Multicrystalline panels are the oldest technology obtainable and in addition the strongest. When sized correctly and paired with suitable batteries, these are the panels to make use of for operating large loads such as refrigeration.

Amorphous thin film solar panels are only about 50% as effective as multicrystalline aerial bundled cables, but can be bought in flexible varieties so they can roll or fold, or change to the shape of a boat cabin top or bimini. They don’t often have adequate yield for considerable energy replenishment, but can be used to lightly charge a battery bank.

How Much Power Can Solar Cells Make?

Normally, we measure solar panels by wattage and that is how we buy them. You can get solar panels for boats as small as 10 watts to as great as 200 watts or even larger. But it is simpler to understand when we change watts to amperage. We calculate these values by multiplying the number of hours the panel is in full sun (usually defined as 5 a day in Florida) by the panel’s wattage. For a 195 watt solar panel the amount produced would be 195 x 5 hrs = 975 watts/day. We can then figure, 975 watts/12 volts = 81.25 amps per day.

Power Consumption

Before considering which acsr wire size to purchase for your boat, you will need to complete an energy budget to ascertain what sources of power consumption you have aboard while at anchor. I use the at anchor scenario as this is the place you will use the most energy; under power and your trawler can supply its needs without any issues.

Example, if you have 3 inside lights that pull 2 amps each and you keep them on for 4 hours per night, your consumption would be 3 x 2 x 4 = 24 AH/Day. We are not concerned by running lights and electronics as they will not likely be running while at anchor.

Mustang Clutch Cables and Quadrants – Everything You Need to Know

After researching this topic in detail in order to solve a problem I had with my mustangs I figured I would share all the information I had gathered so others may learn from my experience.

In between adding an intake, nitrous, and exhaust components, it seems that nary a thought is given to replacing the factory clutch-cable arrangement. That is, until the 4 gauge battery wire breaks or wears out. Then it seems like a good idea to replace it with one of the performance variety. However, there are many options out there and between opinions on the internet, in addition to all the magazine articles/adds, it can be confusing as to which direction you should go. I will attempt to explain the pro’s and con’s, as well as the differences between many of these choices.

Let’s begin with the stock setup itself. The plastic stock clutch quadrant that the factory gave your car is garbage. This plastic part is known to flex under the pressure of a heavier than stock clutch and has plastic teeth that wear down allowing your clutch to self adjust itself into positions that causes the clutch to wear improperly and makes shifting difficult. While an after market quadrant really can’t fix an ailing clutch, proper adjustment of the cable is essential to longer clutch life.

Then there is the cable itself. The h07rn f cable is non adjustable and has a rubber spacer that mates up with the firewall and holds the cable in alignment with the quadrant. It’s construction is also quite vital, but we’ll cover that in a few minutes.

So now you know what you’ve got, but where to go from here? With such a plethora of choices, how do you know what you need? Many companies offer packages that include everything you need to complete the conversion; quadrant, cable and firewall adjuster. However, something that you need to know is that these packages are NOT all the same.

The first choice you have to make is if you want an adjustable cable, or non adjustable OEM cable. This decision will affect the quadrants that are compatible with your setup. I’ve spent time talking with several mustang owners who are very knowledgeable on this subject and the consensus is that an adjustable cable will make for a “harder” clutch due to the increase in drag due to the inferior construction of the cables. The cable on top is your run of the mill adjustable twin and earth cable, while the one on the bottom is an OEM cable.

About five years ago, I installed the BBK package. It included an adjustable cable, quadrant, and fire wall adjuster. Immediately after installation, I noticed that it was much more difficult to engage the clutch than before, a problem that only became worse. Recently I switched back to an OEM cable and immediately the pedal pressure required to engage the clutch dropped. It is because of this incredible difference in pedal pressure that I will never use an adjustable cable again. It should also be noted that it is not just the BBK cable that will cause this as all adjustable cables are made the same, and many people using a variety of adjustable cables have complained of the increase stiffness in their clutch pedal after installing an adjustable cable.

Earlier I mentioned that you must decide between an adjustable or non adjustable cable due to the quadrant requirements. This is because some quadrants can only be used with adjustable cables, some only non adjustable cables, and finally there are a few that can be used with both. Some replacement cables, like the universal cable that maximum motorsports sells has an overall longer length than your stock fox cable but it’s working length is the same. However, all adjustable cables, even if they have the same overall length as your stock cable, have a longer working length than a non adjustable OEM cable. This is where cable specific quadrants come into play. Most adjustable cable quadrants are 3/8 circle in shape. My old BBK quadrant was like this. If using a non adjustable cable you’ll need one that is 1/4 circle in shape or has multiple hooks. This next photo demonstrates this. On the left is a BBK quadrant made to be used with an adjustable cable. On the right is a multi hook UPR quadrant. The farthest throw hook on the UPR piece is made for an adjustable cable while the middle hook is used for a standard cable. The shortest throw hook is used to get around the patent that Steeda has on two hook quadrants.

Electrical Wiring Upgrades: The Safety and Efficiency Behind It

Your home or business’ electrical wiring is an often overlooked component to your electrical system. Many assume that just because the lights turn on and your electrical devices work, that there is no discernable problem your twin and earth cable. However, wiring degrades over time and can pose a significant danger if not properly tested and replaced. Additionally, wiring upgrades can become a sizeable inconvenience if there’s little straightforward planning. Going forward with a wiring upgrade though can ensure your home or business’ safety and allow you to plan for your future energy needs.

The primary reason for considering a wiring upgrade is naturally safety. Any home or building that is over 30 years old may not be up to code and pose a fire hazard. In fact, faulty wiring is one of the principle causes of home fires. Wiring, in general, is typically installed properly. But as a homeowner, unless you were present for the initial installation, there’s no definitely way to determine if the wiring has not degraded.

There are some tell-tale signs that wiring needs to be replaced and they include repeated flickering lights and breakers that repeatedly blow. The key to noticing these signs is that they occur regularly. If such is the case, it almost certainly is a 2/0 welding cable issue. Other signs indicate a more serious danger and include discolored or sparking outlets, burning odors from outlets or appliances, and noticeable static electricity from appliances. These signs indicate a potential fire hazard and should be addressed immediately.

But while an electrical wiring upgrade addresses potential present hazards, it should be also a process that allows you to prepare for your future electrical needs. Many old residences were built with wiring for 60 amps, the past standard for electrical devices. However, today has seen a dramatic rise in the number of amps electrical devices require. Without the proper voltage, many of your high-end electronics will not work properly and could suffer serious damage.

A wiring upgrade, then, is the ideal time to consider your current and future energy needs. The welding cable price list upgrade process is the perfect time to install new outlets in order to alleviate the use of power strips in addition to ensuring that the proper voltage is running to your devices.

While a wiring upgrade is an inherent inconvenience, seeing as it structurally is in your walls, it is nonetheless a service many homeowners should consider, particularly for those with older homes. Going forth with a wiring upgrade now could prevent a potential fire disaster as well as providing you with the opportunity to ensure proper electrical voltage to your new devices.

Electrical Wire Made Easy

There are many different types of h05rn-f cable. Each different kind of electrical wire is perfect for a different job. The wires even have different kinds of insulation and protection; this is what makes each one perfect for a different application. There is THHN and TFFN wires which are very similar. Then there are the NM-B and Romex wires and even the MC Conduit cable. All of these wires are perfect for electrical work indoors and some of them can also be used outside, and in conduit.


Both of these wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. While the THHN stands for thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then throw in that some of the THHN wires come even in a water, gas and oil resistant form, and you get THWN wire. These are all single conductor copper flexible cable types that can be used both indoors, outdoors and in conduit.

NM-B and Romex

Romex is the Southwire brand of an NM-B cable. Now the NM stands for non-metallic. This means that instead of the wire being incased in a metal jacket. The NM-B cable has a PVC jacket around the multiple conductors it holds. Now this version of electrical wire can only be used indoors. The wire does not have enough protection on it to be used outside. The most typical use for this kind of wire is in insulated homes and buildings, running power from electrical boxes to outlets, lights and appliances.

MC Conduit Cable

This kind of electrical cable is very different from the NM-B cable. That is because the MC Conduit cable is metal clad. This kind of electrical cable has an aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket around the wires conductors is meant to act as a conduit so there won’t be a need for one when it’s being installed. This design is also meant to speed up the installation process, in turn saving electricians and contractors both time and money.

Each one of these flexible control cable can be used indoors as building wire. Most can even be used outdoors in conduit as well. Now even though all of these wires are somewhat similar, they are still different, hence the variation in applications. Make sure to check out all of your options to find the right wire for your next job or project!

Welding Cable 2 AWG Compared To DLO Cable 2 AWG

DLO and welding cable are both types of single conductor twin and earth cable with differences that approve them to last in certain applications. There are flexibility, voltage and approval differences in the two electrical cables that will be discussed in detail. You will be able to understand why and why you might not be able to use each cable in your particular situation.

Welding cable is much more common due to personal welding machines, low voltage power applications and industrial welding machines. It is rated for 600 volts with a temperature rating of 90oC. It has a single layer of EPDM rubber insulation that protects the copper strands from outdoor use and rugged handling throughout its life. There is another type of welding cable with UL, CSA and MSHA approvals that industrial applications use and it comes with a much more durable insulation as well.

DLO cable comes in 2000 volts with the same rubber insulation and an additional rubber jacket that helps reach 2000 volts and helps protect it from the common locomotive installation. DLO stands for diesel locomotive and it comes flexible but less flexible than 2/0 welding cable. It has 24 AWG tinned copper strands compared to 30 AWG bare copper strands. The outer diameter of the 2 AWG DLO is .52 inches compared to the 2 AWG welding at .46 inches. The additional jacket is what makes the outer diameter difference in this case.

Electrical cables in 2 AWG come in many different forms which you can understand better when you discuss it with your wire and cable distributor or your electrician. Some are used indoors, outdoors, in conduit and directly underground as long as they have the protection needed to do it. If you need an underground cable in 2 AWG you should see USE-2 solar panel cable because it doesn’t even need to be installed in conduit. You can dig a trench and put this wire directly in the ground without a worry of it not lasting the full life span.

Speak to your supplier about the type of insulation that covers your copper cable. The insulation is what allows the cable to be used in various applications indoors and out. The cost difference is in the amount of engineering, manufacturing and cost of materials which will get more expensive as your move outdoors or underground in this case. Your electrician will help you with the actual AWG size you need in order to meet the NEC electrical code and pass inspection.

WesBell Electronics is an electrical wire and cable distributor of welding cable price list, portable cord, electrical wire, hook up wire and heat shrink tubing. Please let us know if you have any questions about your 2 AWG Welding Cable or any other type of wire and cable you’re installing. We offer Free Shipping on orders over $250 on our website and we cut most of our cables to any length you need.

How to Change Positive Battery Cable

There are a number of functions performed by the battery. It can be out of order due to failure of its cables. There are normally two cables on the battery. Each cable has its own purpose and can be used when it starts functioning. Batteries electrical wire size are signed with positive and negative signs. Each of the sign is presented on the battery. These two signs are completely different from one another and perform different functions. The positive charge on the battery is presented by the (+) sign and the negative sign is presented by the (-) sign. These signs can be seen easily on the battery sides. These signs help to understand the cables attached to the battery.

Any of the batteries can become weak due to its constant use and other internal or external problem. Its cabling can also make the battery weak. A weak battery can not perform its function properly. Especially due to electrolysis and corrosion, it affects the performance of the battery. Your battery power will be less and it will not work. The fluctuation and stoppages will increase. To prevent your battery from such a condition you will have to do some thing which is very necessary and suitable for the battery. You may have to replace the positive power cable manufacturers that is on the it. And its changing does not involve any specialty. It requires time but not so much. There is also a red cable on the battery and two large sections of it. Weak battery will generate weak power and will not pass through easily. It will require extra power to function properly. You should change the cables of the battery especially positive battery cable.

Following are some steps you will have to take when you will replace cable. First of all disconnect all the cables from the battery and hold the battery cable in your hands. Always remember to keep yourself away from the metal on the battery cable because it can be dangerous and harmful. Find out where the positive cable sign is presented; then remove it from the battery. You will not have any difficulty or trouble in doing above steps. Changing a positive battery cable is easy but takes time which is not more than an hour. Now you can re connect the negative battery cable to the battery. It will help the battery to response slowly.

You have replaced the Positive Battery Cable and you have seen that there was not any problem in it. These cables can be purchased from the electronics market. You have also saved your money because you had to call an expert who would have changed the armored cable and would have charged you heavy amount for replacing the cables. Once you change the cables then your battery will start working without any further problem. Batteries and its cables are the most important things in the life of a man. No one can deny the importance and presence of the batteries in today’s world.
