That could only happen if the neutral wire (white) becomes disconnected at either the panel, the meter base or the transformer.
Single pole 20 amp breaker.
You can't.
It depends on where the breaker is fitted. Is it installed in a panel in the US, Canada or another country which also uses the 60Hz, 120 Volts standard supply service?Or is it fitted in Europe or elsewhere using the 50Hz, 230 Volts standard?As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.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-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.The amperage of the breaker dont determine the voltage reading. If your panel is 120v every breaker regarding of amperage rating or size will still read 120v. but to answer your question as it reads... the voltage on the output should read the same voltage as the input or line side.. that is if the breaker is in the on position.
Yes you can, However the wire leading out from the breaker must be rated for 30 or more amps, otherwise there is a fire hazard.
It depends on the voltage source. watts = voltage * voltage / resistance and amps = voltage / resistance example 1: To produce 600W from a 120V source, you need a resistor of size 120V*120V/600W = 24 Ohm. This would pull 120V/24 Ohm = 5 amps. example 2: To produce 600W from a 240V source, you need a resistor of size 240V*240V/600W = 96 Ohm. This would pull 240V/96 Ohm = 2.5 amps.
In America, a 2-pole breaker is controlling 240V. 120V per leg.
you don't run a new 120 line
15 amp breaker.
Single pole 20 amp breaker.
It is 120V/60Hz
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
You can't.
there is 120V across the circuit.

A breaker will not step-down power/ voltage. Its most likely a problem from your suppliers. More likely you aren't measuring the voltage correctly. There is 120 V between neutral and either Hot wire. There should be 240 between the two hot wires. If this is what you are measuring and you are sure the breaker is 240 volts you should be able to measure 240 at the output of the breaker. If it isn't there your panel has a problem.
