No Volt protection is a method of motor starting that ensures personal and equipment safety by disconnecting the power from the motor in the event of a power fail.
If an isolating switch only was used, following a power cut the device could start without warning, and injury or damage could occur. No Volt protection uses push button switches and contactors wired in such a way that when the power fails, the hold on relay releases and the motor will not start until the operator presses the start button.
In most countries this is mandatory, In New Zealand or Austrailia, this is mandated by AS/NZS 3000
120 volts
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.
No, that is too much.
Yes, in the form of GFCI circuit breakers, not as a receptacle.
You need to find the wattage of the pump motor. This is found by multiplying the voltage of the motor by the amperage of the motor. Once you have this figure use it to find an inverter that can handle this wattage load at a 240 volt output.
All motor circuits require protection against single-phasing.
The protection is there to prevent motors starting up on their own after a power failure. This could lead to very unsafe conditions. Also in a big industrial factory if everything started up at once the demand load could trip the main breaker. With the protection in the circuit each and every motor is started up independently.
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
it may cause minor damage, such as burning out the fan motor, if unplugged quickly, or it may fry the compressor or any electronic circuits in the fridge.
Divide the circuits amperage into the volt amps and you will get the voltage.
120 volts
You can but the motor may not run, however you will not burn the motor.
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
NO
There are two circuits on the battery and motor. One wire is take which have four ends. The wire is connected on the desired circuits.
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.
No 380 volts is too wide a spread to use a 220 volt motor on.
