Four electricians are discussing voltage ratings of circuit breakers. Electrician A says that a circuit breaker marked 120/240 V is acceptable for a circuit that doesn't exceed 220 V between any two conductors. Electrician B says that a circuit breaker marked only 240 V wouldn't be acceptable for a circuit exceeding 220 V between any two conductors. Electrician C says that a circuit breaker marked 120/240 V is acceptable for a circuit that exceeds 220 V between any two conductors. Electrician D says the 120/240 V breaker would be acceptable for a circuit that doesn't exceed 240 V between any two conductors. Which electrician is correct? A. Electrician D is correct. B. Electrician A is correct. C. Electrician B is correct. D. Electrician C is correct.
