The ground wire also connects to the switch but the white wire gets spliced to the circuit neutral wire and bypasses the switch. Any circuits black wire should be considered hot or live.

Black white red wire. Black electrical wire is used for power in all circuits. The standard way to power a split tab outlet is to run a three conductor cable to a wall switch. The different colors of electrical wires indicate the function of the wire with black and red indicating the wires carry electric current white usually indicating neutral charge and green indicating the wire is grounded. Black wires are always hot wires meaning that they carry electricity. One of the hot wires attaches to a brass terminal on one side of the outlet and the other attaches to a brass terminal on the other side. The white wire is the neutral and all other colors are hot.
Electricians often use black red or blue wires to deliver electricity to a circuit from the main panel. They may use other colors for. When measured with respect to the white neutral wire the red wire carries the same 120 volt current that the black one carries making the voltage across these two hot wires 240 volts. The cable has a black wire which connects directly to the circuit and a red wire which connects to the switch. How to connect the black white red and green wires of a ceiling fan the red wire from the junction box connects to the blue wire on the ceiling fan. The colors regulated by the national electrical code in the united states are standardized for safety.
Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet. The bare copper wire from the junction box connects to the green wires on the ceiling fan.
