This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

∙ 14y agoAn electrical sub panel is a smaller version of the main panel. It is a way to move many circuits to a point further away from the main panel instead of taking many single circuits from the main panel board. The sub panel has just one supply feed from the main panel. By using a sub panel there is a cost savings in labour and materials. On larger buildings there may be multiple number of sub panels. The amperage rating of the sub panel board governs the size of the wires and the breaker used in the main panel to feed it.

Is a cu wire a ground wire?
The type of wire does not generally determine whether something is a ground wire or not. A wire is a ground wire if it is connected to the ground of a circuit, or the common ground (the reference point of a circuit that is at 0 volts). However, in relation to the grounding rod used to connect the main circuit panel for a house, the rods are almost always made of steel that are copper plated.
Does the ground wire from a 240 volt tankless water heater connect to the common wire?
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
What size wire and circuit breaker is needed for an electric oven 4 wires with rated load of 34.9 amps 220v that is about 100 foot run from the electrical panel?
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
How do you wire floating neutral in sub panel?
You need to be more specific. Is this your feed?? Is this a home run (the wire that is feeding a circuit). Anyway if this is your feed wire (the wire supplying power to your sub panel) then you will land your two hots , then you will land your ground wire on the lug that is bonded to the panel. Sometimes this is a ground bar that can be screwed to the panel itself and then your neutral will go to the bar that is not touching anything. So your neutral coming in will be tightened down to the same bar as the neutrals that are feeding the circuits. This is assuming you'r are feeding your sub panel with 2 hots, a ground and a neutral.
What wire carries the electrical current to the appliance?
The black wire is the hot wire through which the electrical current flows to the appliance. The left over voltage which is usually zero flows back to the main circuit panel through the white neutral wire where it flows to ground.
What is a branching circuit?
Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.
What is the earth wire inside a plug for?
This wire provides a low impedance return path to the distribution panel in case of a circuit fault. This direct fault current path will trip the circuit's breaker and open the circuit.
How could you get more than one electrical circuit in the garage?
Run another wire from the electrical panel.

Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
What size wire to feed a panel with 50A breaker for hot tub and 20A branch circuit?

How do you change burned out bulbs in control panel in 1995 Camry?
Change the fuse controlling the control panel lights. You need to check wire harness around the panel because you have to high voltage in the circuit.
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.
How can one circuit of a 4 four circuit service panel be providing 136v AC and the others 106volts when the incoming power is 240volts from the meter?
The neutral wire is open, or has a bad connection.
I am wiring a circuit in my shop to run a MIG welder that draws a max of 30 amps The run is approximately 40' from the service panel What gauge wire should be used for this circuit?
