- 2 hot wires, containing 120 volts each, run through the main shut-off switch and connect to the 2 bus bars that run down each side of your main panel. Individual circuits attached to these bars feed the electricity to the different plugs and switches in your home.
- 1 neutral wire runs through the main panel and gets fed to the ground for safety. Circuit breakers at the head of each circuit re-route power to this neutral ground wire when the voltage exceeds a certain limit. A properly wired home electrical system will allow you to run all your appliances at will, without any flashlight trips to the basement or garage.
- Standard plugs and light switches are connected with 1 hot wire (usually black or red), 1 neutral wire (usually white), and 1 ground wire (bare copper).
- Larger appliances, such as your washer and dryer, are connected with 2 hot wires and 1 ground wire.
