Electric repairs at home usually involve wiring issues. If you are thinking about getting into an electrical project, it would be best if you have an idea about the different kinds of wires and how to install them with the right connections. Learning the basics of various electrical wiring and materials will help you minimize errors and reduce purchasing costs. It will also help you investigate what problems need to be addressed immediately.
- Proper Wire Size
One critical issue in any wire installation project is choosing the right size of wire. An electrical wire sizing indicates metal conductor diameter. Its gauge is relative to the current capacity of the wire and the amount of amperage which the wire can handle. In choosing the wire size, you have to know where it will be used. Most home wiring installation is done with a non-metallic cable which is made up of three or more wires wrapped in a sheathing inside. It is usually used for switches, outlets and lighting fixtures.
- Color Coding
Electrical wires and cables have colors to help you identify what it is used for. The cables are colored in relation with the size of the wire inside as well as the amp rating. White non-metallic cables is generally used for circuits that have 15 amperage while the yellow ones are for 20-amperage circuits. For electrical wires, the black ones are typically used for current-carrying connections while the white wires are for neutral conductors.
- Letters and Numbers
The outer sheathing or installation of the cables and wires have marking printed and stamped on them. These markings will provide you with information as to the insulation and wiring of the materials. You’ll find information that includes the material and wire size, number of wires contained inside and other special characteristics or ratings of the wire. Looking for this particular marking will help you identify and narrow down your choices when buying electrical wires and cables.
Buying an electrical wire and cable is not simple. If it’s your first time, you’ll most likely become overwhelmed as to the wide choices that these electrical materials actually have. It would definitely come in handy if you have enough information as to the type of and kind of wire that you will be using for your electrical project at home. This way, you can cut the shopping time and reduce the purchasing cost, as well.
