The voltage of 277 volts is the wye voltage of a three phase 480 volt distribution. In the 480 volt CDP (Central Distribution Panel), you will need a 600 volt rated single pole 15 amp breaker installed in the CDP. The load will be connected to the output terminal of the breaker and the other conductor will be connected to the neutral bus in the CDP. The minimum size conductor for the 15 amp circuit will be a #12 copper conductor.

How do you wire a 240 volt street light circuit?
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
Is there a way to install a 277V light on a 120V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
A 24 volt battery supplies three devices wired in parallel that each have a resistance of 9 ohms. What is the voltage drop across each device?
A simple circuit has three resistors connected in series. The resistors are 14 ohms 12 ohms and 9 ohms. What is the total resistance of the circuit?
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.
How is the total load in volt-amperes for lighting purpose determined?
LxW of building x 3 volt amps per sq. foot
Can a 266 volt heater be wired to 480 volt circuit?
No, it would overheat, might blow the fuse, otherwise it might catch fire.
Is the voltage on a 120 volt fluorescent lighting circuit the same from line to neutral and line to ground?
Yes, to the precision you can measure it. If it isn't you need to check the ground to neutral bonding at main panel and check the wiring in the circuit for loose connections.
Is there an adapter that will make a 110 volt refrigerator receptacle into a 220 volt?
No. You need to rewire the circuit from the electric panel.
Can you plug your natural gas furnace into a 120 volt receptacle?
The furnace can be but it is not a good idea. Safety code requires a disconnect switch outside the area where the furnace is situated. This switch is used for an emergency shut down in case something electrically goes wrong with the furnace. In modern homes these furnaces are wired to a dedicated 120 volt circuit from the distribution panel. From the panel, the circuit is routed to the safety switch. From the safety switch, the circuit then continues to the furnace load.

How do you connect 230 Volt single phase to a 440 circuit panel?
You can't get 230 from a 440 panel. You'll need a step down trandormer
How do you connect a volt to a circuit?
A volt can not be connected to a circuit.
What circuit breaker to install for 10 amp 250 volt circuit?
You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.
How do you wire a 277 volt heater from 480 volt box?
Answer for USA, Canada and countries running a 60 Hertz supply service.The 277 volt heater can be wired to a single pole breaker in a 3 phase 4 wire 480 volt distribution panel. The breaker should be sized to the amperage draw of the heater. 277 volts is the star point (wye) voltage of a 480 3 phase system. 480 / 1.73 = 277 volts. The third answer is not correct, two phase legs of a 480 volt system will give you 480 volts. It is the phase leg to ground (neutral) that gives you the 277 volts.A 277 Volt heater or device may not be wired to a 480 Volt circuit or box. A 277 Volt device may only be wired to a circuit rated for 277V/480V equipment.2 legs of 480 volts will give you 277. But since you don't know the answer you probably shouldn't be doing it! Please don't kill yourself, hire a licensed electrician.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What size neutral for 60 amp circuit?
what kind of circuit? if it's a subfeed from one panel to another same size as hot wires. if it's a straight 240 volt circuit #8. depends on what kind of circuit.
