On my breaker panel, I have 2 15 amp breakers that were used for a baseboard heater. Connected to the breakers are one white wire into one breaker, and the black wire goes to the other breaker. The throws of the breaker are connected together with a metal clip. They are 2 independent breakers connected together. Does this mean they are being used to produce 30 amps? If I want to use 15 amps from one of the breakers, do I remove the white wire and connect it to the common neutral bus and the breaker with the black wire will be in use breaker? This breaker will be used to supple power to my shop, where I have 3 receptacles. Does this make sense? It does to me, but I want to confirm with you guys before I get this done. Thanks.
