The 7300 120v input has only two wires, black and white, no green. Black comes from the breaker and white on the neutral buss with the rest of the 120v whites.
On some/many/all 7300s the converter shares its breaker with the receptacle circuit breaker -two black wires from that breaker.
So the question is what happens if the new (or the original) converter's black and white input wires are reversed so the white is on the breaker and the black is on the neutral buss.
Will the rest of the 120s even notice? Will the receptacles' GFCIs be affected? Will the converter itself notice? (apparently it runs ok. Old two prong plugs didn't matter which way you plugged them in)
