Hello everyone,
I don't know if this has ever been discussed or not, but here I go. When using a shared neutral, say for instance when wiring a dishwasher and disposal on a 3 wire, how should the circuit be breakered? I have always used a double pole breaker for this application, where the place I work now, uses single pole breakers. I was always told that, reguardless of how the circuit is wired at the "device" end, it should always be breakered with a DP breaker because even if the one device is turned off, say in a lighting circuit or a receptacle circuit(it's a shame I can't draw a picture to help explain it better), there is a potential voltage on the shared neutral. Is there also a section of the code that explains this? Any info would be greatly appreciated.
