If you're thinking about becoming an electrician or just want to know how the wiring is done, you should keep reading. The Youtube video "Electrical 101: Basic Wiring Knowledge" shows the main aspects of wiring you should understand. Let's find out more!
The video shows the main panel and how it's set up while the walls of a house or building have not been finished yet. You get a detailed view of how cables and wires are placed around your house and how they flow through the walls to power what you need.
There's a power wire or several coming from the main panel or power source, which connects to a power box. From that box, you get more power cables that connect to other boxes to distribute electricity properly. Some of the wires from the power boxes will be assigned to the lights, and they can also be called switch legs.
Each power wire has three sets of tinier cables inside: the green, black, and white cables. The black wire is the actual electricity or power wire. To install the switches, you have to split the power wire to turn it into two.
