When at a 2 pole light switch and the wire colors shown are black white and green which is the hot wire and which is the common?
the black wire is the hot wire
Should grooved wire be connected to white wire?
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
Which of the two wires is hot which is neutral?
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
What is black wire use for?
In household wiring it is the "hot" wire that carries current to the load.
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.
Which is the hot wire if there are both black and red wires?
both
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.
If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot wire?
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
Which wire is hot black with a white stripe or solid black?
The normal practice is for the black (or at least darker) wire to be hot. However, given the consequences of guessing wrong, they should be tested and both wires should be treated as "hot" until you find out differently.
When at a 2 pole light switch and the wire colors shown are black white and green which is the hot wire and which is the common?

How do you wire a light switch with only black and red wires?
Connect the black wire to the incoming hot wire and the red wire to the out going load.
Should grooved wire be connected to white wire?
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
Would the black wire be line 1 on 240V line in?
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
What to do with the white wire in track light with black green and white wires if the house does not have a white one?
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the white and green to the other wire.
Which is the positive wire between a white and black wire?
That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.
How do you wire an up down switch?
You only have to break the black wire because it is the hot wire.
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.
