I was on a job, not mine, and the guy had me wiring up some relays to control an appliance. I did as he asked, but the install just didn't seem right. I don't see anything dangerous, but do see code violations (I think). I just want to know if I'm the only one who cares about this kind of stuff. I always try to be code compliant if for no other reason than to pass inspection.
The circuit feeds a range. The two ungrounded conductors leave through the top of the panelboard, through a 3/4" conduit 3" long, and into a 12"x12" box. In that box they connect to the line side of a general purpose contactor. Then, off the load side, they exit through another 3/4" into the original panelboard and meet up with the neutral and they all leave together to the range receptacle. The 120v coil of the contactor is fed from a tap off of the line side of same contactor, and is controlled by a 24vDC ice cube relay in the same box. A 12awg grounded conductor is routed from the neutral bus in the panelboard, up to the box through one of the 3/4" conduits to power the 120v coil. I realize that this is going to work problem free, but is it wrong? Opinions?
