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.
