[QUOTE="Tim McCulloch, post: 58152, member: 67"] Re: Lighting system causes buzz/hum in the circuit breaker panels The dimmers are dumping harmonics back up the neutral line.... which makes me wonder about the electrical service in the venue. Machine shops use 3 phase DELTA, which has no neutral. I think you need to have an electrician look at how the transformer for the 3 phase WYE was installed and bonded to ground. [/QUOTE]
