Quais são os principais pensadores da história? - WebMinimum Circuit Breaker Size = A × = Amps We can’t use a 15A breaker because the breaker ampacity should be at least A. The next breaker size is 20 amps; that means we need to use a 20A breaker for a 1,W space heater running on V standard circuit. A standard 1,W space heater on a V circuit requires a 20A . Web · Circuit Breaker Voltage Ratings. Low voltage (under volts) circuit breakers are commonly rated for, volts, volt, or volts AC. Some breakers are rated for used in DC circuits, while others are rated for use in either AC or DC circuits. Answer: The value of the maximum service voltage must be written on the body of the circuit breaker. In no case, the mains voltage can be higher than this value.
