What does 277 vac mean?
That's 277 volts of alternating current. This is typically one phase of a 480v 3 phase system. Don't worry that 3 x 277 adds up to more than 480v. A 277v line is typically one phase of a 480v 3 phase system.
How do I rewire an ungrounded plug?
If there is no ground wire connect the ground wire to the neutral wire.
What are the wire colors for 3 phase 440 vac?
R - Red Y - Yellow B - Blue
Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
What size wire is required for 277 volt fluorescent lighting?
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
Can you connect 2 wire to 3 wire house has black white red and ground Appliance has black white and ground?
It seems like you are describing the Red, Black, White and Ground in your electric panel. There is 240 VAC between Black and Red and 120 VAC between Black and White and 120 VAC between Red and White. The electric panel has two busses that supply 120 VAC on alternating breakers in your panel. Essentially, the Red turns into "black" in the panel for all practical purposes. If you have a 240 VAC circuit it essentially takes up to two vertical positions in your electric panel.
What is the ac voltage reading between the bare copper wire and the hot black wire 120 vac or zero volt?
Should be about 120 VAC.
How do you wire a 220 VAC 4 wire cable into your breaker box?
If you are talking about a 4-wire branch circuit you'll need to start with a 220 VAC breaker. It will have two terminals. Connect black and red wires to the two terminals. Doesn't matter in which order you make this connection. The white wire goes to the neutral bus bar where all other white wires are connected. The green or bare wire goes to ground bus where other bare wires are connected.
How do you wire 250 watt metal halide 277v with only one line and one common?
That is all that is needed to wire the fixture. The 277 volts is the line to neutral of a 480 volt three phase system. Any one of L1, L2 or L3 to the neutral will give you the 277 volts that you need to connect the fixture so that it will operate.
Testing a power io DAA-6V100 solid state contactor?
Use a small light bulb, such as 25-50 watt. Connect 120 VAC power to the big L1 terminal. Connect the big T1 terminal to the light bulb. Connect the neutral to the light bulb. The light bulb will be OFF. Connect another 120 VAC wire to the control input terminal #3. Connect another neutral to the control input terminal #4. The light bulb will now be ON.

How do you connect the wire from the alternator to the starter?
how do you connect the wire from the alternater to the starter?
In WYE 480VAC each leg to neutral is equal to how many volts?
In WYE 480 VAC each leg to neutral is equal to 277 volts. 480 / 1.73 (sq root of 3) = 277.
Can you wire a 240 volt window ac from a 277 volt feed?
no

How do you wire a sub in a Saturn sc?
Connect the sub woofer to the equalizer or amplifier. The positive wire will need to be connected to a power source. Connect the ground wire. Connect the auxiliary wire to the amplifier.
How do you wire a 3 wire exhaust fan to a 4 wire outlet?
The fan is probably a 115 VAC single phase fan and the outlet is probably a 230 VAC "two phase" outlet. The fan would then have the following wires: hot (black), neutral (white), and ground (green). The outlet would then have the following wires: hot #1 (black), hot #2 (red), neutral (white), and ground (green). Pick either of the two hot wires on the outlet and connect the hot wire of the fan to that (ignore the other hot wire on the outlet) and connect the neutral to neutral and ground to ground. If the wire colors are not as I described above you may have something else (e.g. 3-phase) and that would be wired differently, but those systems are usually used only in industrial settings not the home.
What color wire do you connect to the dimmer wire from radio?
Don't connect the red wire or you will die.
