Factors affecting the selection of electrical conductors
Electrical wiring is used in virtually all types of settings with all kinds of requirements. The truth is that a wire that is perfect for one application may not be the best choice for another. But since they come in a wide range, you will always be able to choose the best one for the wiring project you have and any specific requirements that may arise. Here are some of the factors that influence your choice.
Labeling – If you are keen enough, you will find that the electrical wires have letters on them. They usually represent types of isolation. For example, one labeled H means it is heat resistant, while one labeled HH means it is highly heat resistant. T can stand for thermoplastic insulation, N for a nylon coating that is resistant to gas and oil damage, and W can mean the wire is suitable for wet conditions. They can come in multiple letters to denote different properties. If you are not very sure about the type to buy, seek professional help or make inquiries and go through the reviews to understand the specifications.
Load in watts, current and gauge – These are very important considerations to help you get the right wire for the right application. The load in watts indicates how much power it can handle, the amplitude means the amount of electricity that can flow through the wire, and the gauge is simply the size of the wire. These aspects are mentioned on the appliances, making it easy for you to know which cables to choose. Of course, you can get help from an electrician if you are not very sure about the interpretations to help you find the most suitable one.
size – Each application will ship with a specific size that is suitable for installation. The gauge of the wire is what determines the size, with the most common wires being 10, 12 and 14 gauge; the higher the number, the smaller the wire size. The size of your wire is important because it can affect the amount of power it can handle.
Color codes – When it comes to electrical wires, different colors serve different purposes. The black ones are usually used for contacts and switches, while the red wires may be ideal for switch legs. The bare copper and green wires are for ground, while the white is always neutral. Some are best for all types of internal wiring, especially in appliances; your app should help you choose the correct color code.
Wire type – Electrical conductors come in a variety of types, including triplex, panel feeder, main feeder, single core and non-metallic sheathed conductors. Your application will again determine which wire type is best. When you buy your cables, you can always get professional help choosing and possibly even installing whatever you’re working on. Improper use of a wire can have serious consequences and they are what you should try to avoid.
