The Aluminum Conductor MC Cable Buyers Guide
Electricity has been one the greatest invention ever on the surface of the earth. The invention of electricity called for a means of power distribution and hence the need for cables. Cables evolved and more innovative ones are churned out every year to match specific needs. Electrical cables have continued to be utilized in and around residential buildings, industrial and commercial buildings. They operate by supplying electrical power an electrical box in your house and then distribute it in your entire home. Depending on the kind of connections installed, others will need small amounts of power for instance light switches while others will require larger amounts of power. Aluminum conductor MC Cable is a kind of electrical cable that is used in applications such as power lighting, branch circuits, and cable tray and service feeders as has been spelt out by the National Electrical Code.Read More
What is an MC Cable?
MC is an abbreviation meaning Metal Clad due to the aluminum interlocked armor used as a jacketing material rather than the typical Polyvinyl chloride (PVC). An MC Cable is quite outstanding as compared to other electrical cables even in terms of structure. The metal clad in this case wraps around the conductors.
This serves as its own conduit for indoor applications and enables the cable to be used outdoors and in- conduit underground. You should note that using this cable directly in the ground is not possible unless you go for an MC Cable with extra PVC jacket. The move to go for one with extra PVC will cost you a lot as it is much more expensive. Differentiating the ground wire in MC Cable from other electrical cables is quite easy as it is insulated in the color green.
Why go for the aluminum conductor MC cable?
The reason why the 600 volts aluminum conductor MC cablefor instance has continued to gain popularity is because it has great benefits in comparison to other electrical wires and cables. To begin with there are a number of savings you will make when you move to MC cables from pipe and wire for branch circuits. By moving to aluminum MC cable you get to cut down your entire installation budget by almost 50% on each task. This MC Cable comes with protection attached to it.
MC cables have their own armor and so the need to use electrical conduit is not necessary. The cable has been pre- assembled and pre- tested making it fast to install and safe for use. Installation will require you to move about carrying it around. If it is heavy, the installation process will be somehow slowed down. But the good news is that this one is of light weight nature and therefore saving the time spent on installation.
The aluminum used in the construction of this cables has unlimited bends. This in turn improves the flexibility of the cable during installation and termination process. Flexibility allows one to bend and cut the cable according to his or her needs. Bending conduit is one skill that one needs to learn and can be a very complicated one to master. With the unlimited bends you will find it easier to use the MC Cable as you do not need to bend a thing.
As there is no necessity to bend or install conduits, the need for special tools is not required. Standard cable ties are used to fix the cable to the wall. If need be, the cable can be routed in ducts.
When compared with other electrical cables, aluminum conductor type MC cable attracts very low material costs. When carrying out installations, be in the know that it is suitable for vertical applications only.
In the event you need it for encasement in concrete and for direct burial, you can get the cable availed to you with polyvinyl chloride.
Parts of an aluminum conductor MC cable
Just like any other cable, this one comprises of various parts making it outstanding when compared to other electrical cables. Lets us now look at the components that make up an aluminum conductor MC cable.
The conductor of any electrical cable is a major part. This is because it carries electrical current from one point to another. As such it needs to be constructed with the best material that is reliable and durable. The conductor of this metal card cable is made of compact stranded 8000 series aluminum alloy. It comes in sizes 6 AWG through to 750 KCML. The neutral conductor for 120Y/208 volts circuits is colored white while those with 480Y/ 277 volts circuits are colored grey. There is a binder tape that cables together all the conductors. This separator tape has an identification print to be easily noticed.
Insulation protects the conductor form getting physical and mechanical damage. Therefore a material with great resistance to physical and chemical damage is of higher likelihood to be used. Depending on the type of aluminum conductor MC Cable used, you might find some cables insulated with cross- linked polyethylene (XHHW-2) or Thermoplastic High Heat- resistant Nylon (THHN) or THWN- 2 insulation. The insulating material is normally color coded for easy identification. These insulation materials enable the cable to be used in both wet and dry locations. The insulation of the cable ground comes in either bare or green to be easily pointed out.
An armor works to protect the entire cable, both insulator and conductor, from all kinds of damage. The aluminum conductor MC cable has an overall aluminum armor interlocking over the assembly of the conductor.
