240 volts maximum.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.
0.016 volt
On most residential circuit breaker boxes in North America, each individual breaker represents one 120-volt circuit. Two breakers ganged together represent a 240-volt circuit.
1 million volts.
Yes, all breakers have an insulation factor as to the maximum amount of voltage the device can be subjected to. A 208 volt breaker has a maximum up to and including 240 volts. A 480 volt breaker has a maximum up to and including 600 volts. A higher voltage rating breaker can be used on lower voltages but not the other way around.
If you never plug anything into them, there is no limit. If the total current drawn from all outlets exceeds 20 amps, the breaker will trip.
For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.
Answer for USA, Canada and countries running a 60 Hz supply service.To operate a 240 volt load in the home you use two adjacent breakers. This will give you a voltage of 240 volts where as one breaker to neutral will give you 120 volts.
In North America a two pole breaker will be used in the distribution panel for a supply of 240 volts for a 240 volt load.
