Whether you’re planning home remodeling or doing a simple repair, it’s important to know the basics of electrical wiring. The more you understand, the easier it will be to diagnose problems and make the right connections. You’ll also be able to buy the right wire and avoid mistakes that can lead to fire hazards, common electrical issues in KL factories, and other costly errors.
What is the importance of wiring diagram in electrical works?
A wire is an insulated conductor that can carry current (either AC or DC). A cable, on the other hand, is a bundle of two or more wires connected together with a sheath. The sheath of cables is often color coded to indicate the size of wires within, as well as the cable’s amperage rating.
Insulated wires may be run in any number of ways between electrical devices. They can be run in a specialized bendable pipe called a conduit, or in one of several varieties of metal or non-metallic tubing. They can also be run in a rectangular cross-section metal wire trough, or in PVC tubes known as ducts. Wires may also be buried underground, or run inside concrete in severe pulls.
In homes, most circuits are wired with NM cable (Nonmetallic sheathed). This type of wire is available in many different gauges, and each has its own purpose. The most common uses are for outlets, switches, light fixtures and appliances. The most important thing to remember when choosing a type of wire is that the installation must be up to code, and this means following both national and local codes. Failure to follow code could result in a dangerous electrical system or a costly fine from a home inspector.
