What colour wire goes to the breaker using 12-2 wire?

For a typical 12-2 wire, the black wire is the "hot" wire that connects to the breaker, the white wire is the neutral wire that connects to the neutral bus bar, and the bare copper wire is the ground wire that connects to the ground bus bar in the circuit panel.


Negative 12 volt wire?

A negative 12 volt wire typically refers to a wire that carries a direct current voltage of -12 volts. It is commonly used in electronic circuits and power supplies where negative voltage is required as a reference point or for specific functions. Make sure to follow proper safety precautions when working with negative voltage to avoid electrical hazards.

What is the proper wire nut size for 12 2 wire?

For a 12-2 wire (which consists of a black insulated wire, a white insulated wire, and a bare copper ground wire), you should use a red wire nut. This wire nut size is designed to accommodate two to three 12-gauge wires, which is suitable for connecting your 12-2 wire.


What is the difference between 12 -2 and 14 -2 wire?

Both 12-2 and 14-2 wire have 2 wires in a single cord. Neither contains a ground wire. Size 12 wire is a larger wire than size 14 wire. Size 12 wire can carry more amperage without getting hot and burning up. They would not be used for house wiring or machinery since they do not have a ground wire.


What would occur if you switch from 14 wire to a 12 wire?

12 wire is bigger than 14 so nothing would happen, the bigger the wire the more current it can handle and the better it is.
