Some control circuits remain at line voltage but most use a reduced voltage of 120 volts. This is acquired by the use of a control transformer 480 primary to 120 volts secondary.

Are Ground fault circuit interrupter GFCI devices available for use on 240 volt 480 volt and 600 volt circuits?
Yes, in the form of GFCI circuit breakers, not as a receptacle.
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.
Is sj cord rated for 300 volts to be used for 480 volt?
No. The voltage rating needs to be 600 volts for 480 volt power.
Can a 575 volt drive power a 480 volt motor?
No, that is too much.
Can you run a 570 volt motor on 480 volt three phase power supply?
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.

Yes, in the form of GFCI circuit breakers, not as a receptacle.
What voltages do industrial electricians work with?
480 volt amperage and up to higher voltage
Can you run 480 volt motors in a 380 volt system?

Can 480 volt electric be run in emt conduit?
Yes 480 volt electric wiring can be run in emt conduit.
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares

Should 2 legs of 480 volt 3 phase each have 480 volts?
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
Will a120 volt meter blow up if installed in a 480 volt installation?
Yes
