Question: Which wire goes where on a switch?

When you turn on a light switch, power goes to the light through the “hot” (black) wire and then back through the neutral (white) wire to the ground. The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault.

Which wire is hot on a light switch?

black wire Electrical Wires The black wire is the hot wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the neutral wire, which takes any unused electricity and current and sends them back to the breaker panel.

What color wire goes to the switch?

Hooking up a switch is the essence of simplicity. You connect the black wires in the electrical box to the switch terminals, and the white wires to each other. The switch also has a green terminal for the ground wires, which usually are bare.

Why would a light switch have two hot wires?

The wire from the other switch is almost certainly the line hot. If so, it will be always hot no matter what position either of the switches is in. This is electrically the same as having a separate wire going to each switch from a common line hot.

Can you wire a light backwards?

Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
