How to hookup and fuse electric heaters on a 220-volt circuit?
I am wondering how to hookup and fuse electric heaters on a 220-volt circuit? We currently have a 12-gauge wire where both the white wire and the black wire are connected to the live (hot) feed from the 220 volt breaker at the breaker panel. We are wondering whether or not there are 2 return (neutral) wires returning to the breaker panel, or maybe these aren’t necessary somehow. It is not obvious to us at the moment.
Thanks for any advice on this.
Each of those wires has 120V AC on it but 180 degrees out of phase with each other giving you 240V AC across the black and white wires. You do not need a neutral in that case but the ground wire is essential for safety. You are probably connected with a standard 12-2 w/gnd cable and there is nothing wrong with that. It is the same way the oven elements work in your range. The exception is there is a neutral wired to the range to give you 120V for the stove top elements and clock, lights, etc.
