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.
If there is no ground wire connect the ground wire to the neutral wire.
R - Red Y - Yellow B - Blue
The neutral wire and power wire are never connected together.
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.
Yes, you can connect the black wire from the appliance to the black wire in the house, the white wire from the appliance to the white wire in the house, and connect the ground wire from the appliance to the ground wire in the house. The red wire in the house can be capped off safely as it is not needed for this appliance.
Should be about 120 VAC.
To wire a 220 VAC 4-wire cable into a breaker box, connect the black and red wires to the circuit breaker terminals for the hot wires, the white wire to the neutral bus bar, and the green or bare wire to the ground bus bar. Ensure the breaker is turned off before making any connections and follow local electrical codes and safety precautions. If you are unsure about the wiring, consult a licensed electrician for assistance.
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.
how do you connect the wire from the alternater to the starter?
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.

no
In a WYE 480VAC system, each leg to neutral voltage is approximately 277 volts.
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.
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.
Don't connect the red wire or you will die.
I connect the red wire to the blue wire to deactivate a bomb.
