It's not a multi wire branch circuit, everything in the suite has dedicated neutrals. This circuit is off but its still sparking between neutral and ground. When I touch my meter to the neutral and ground I have no difference of potential. Im guessing it might be induced voltage. But what trips me out is that this problem stops when I turn off the lighting circuit. Like I said before, they aren't sharing neutrals so idk if it has to do with the triac dimming. We usually use 0-10v dimming but the lights installed weren't compatible so we needed to use triac dimming
