CoachFor 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.

How many 250-watt 240 VAC HPS fixtures can be installedon a house with a twenty-amp breaker?
Assuming each 250-watt fixture draws about 2.1 amps, you could install up to 9 fixtures on a twenty-amp breaker. This calculation is based on the formula for determining amperage (Watts / Volts = Amps) and the maximum continuous load of an electrical circuit being 80% of the circuit's rated capacity.
How does you caluclate the Horse power in 250 amp circuit breaker?
The horsepower rating of a 250 amp circuit breaker can be determined by using the formula: HP = (V x A x Eff) / 746, where V is the voltage (in volts), A is the amperage (in amps), and Eff is the efficiency factor (usually 0.8 for typical motors). Plug in the values and calculate to find the horsepower rating of the circuit breaker.
Can you put a 120 v receptacle on a 240 v circuit breaker?
No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.
30 amps on a 250 volt outlet can handle how many watts?
A 250 volt outlet with 30 amps can handle up to 7500 watts (250V x 30A = 7500W) of power. This calculation is based on the formula Watts = Volts x Amps.
What size circuit breaker should be used on 125 feet of 4 AWG power feed?
The circuit breaker is used to protect the conductor that is connected to it from an overload condition. On a motor load the breaker has to be sized 250% of the motors full load amperage. Some circuits can be only loaded to 80% capacity and this is governed by the sizing of the breaker. Without knowing what the load amperage is, this question can not be answered.
