Answer for USA, Canada and countries running a 60 Hz supply service.The Hot wire should be black and the Neutral wire should be white.

To further ID the wires, use a voltmeter.

Measure between the Neutral and the Hot and you should have current (120 Volts?).

Measure between the Hot and Ground and you should have the same current. Between the Neutral and Ground there will be no current.

If you don't have a voltmeter, you can use a lamp rated for the current in the wires you're trying to ID (ie, a 120 volt lamp if it's a 120 volt circuit).

Wire the lamp between the Hot and Neutral, and it should light up.

Wire the lamp between the Hot and Ground, and it should light up.

Wire the lamp between the Neutral and Ground, and it should not light up.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

What wire is the hot wire and ground wire in a 1990 cutlass supreme?

the hot wire goes to the starter and the ground wire bolts to the engine block.


Why Is the ground wire hot?

No it is not.


What happens if neutral and hot touch each other?

If a "hot" wire contacts the "neutral" or ground wire, electrical current flows to the ground.


Is a copper wire a ground wire?

Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.


Is the striped or the solid wire hot?

White is typically neutral and black is hot. If you are talking about the bare wire, that is ground.


Why is the ground wire hot at all outlet boxes on a particular circuit?

Most likely the ground (green) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! Possibly you meant the neutral wire not the ground wire, in that case most likely the neutral (white) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! In either case check all three wires in the breaker panel for that circuit to make sure they are all correctly connected! Black is hot, White is neutral, Green (or uninsulated in some cases) is ground.


Is the ground wire safe to be the hotwire?

No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.


My Windshield wiper motor stop working for my 1995 cutlass supreme. Can you tell me which wire is the hot wire and the ground wire?

Red is hot, black is not.


Can a insulated ground wire be used in lieu of a tinned bare ground wire?

Yes, as long as it is the same size wire or larger as the hot and neutral wires.


Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?

Brown = Hot Blue = Neutral Yellow/Green = Ground


Where does the ground wire go on a car battery?

Negative - (Black) is Ground, Positive + (Red) is Hot. Ground wire goes to Negative (Black) it goes from negative on battery to engine for ground.


What do you usually mean by hot wire?

That depends on the context. In the case of a vehicle, if you "hot wire" the ignition it means that you have bypassed the keyswitch. In the case of the electric service to your home or business, the HOT wire is the one that carries the current. The ground wire is literally connected to a rod that is driven into the ground. The neutral wire (according to code it should be white) is connected to the center tap of the transformer and if everything is functioning properly there should be little or now voltage potential to ground. Leaving the BLACK (or red) wire to be the HOT wire.
