[QUOTE="David Buckley, post: 64448, member: 2235"] Re: Lighting system causes buzz/hum in the circuit breaker panels Using one's ears is very good advice. If one stands next to a transformer, if one hears the deep hummmmmm of the fundamental, then that is lovely. If one hears the buzzzzzzzz of the third harmonic, one knows there are triplens present, and one ought to expect big neutral currents. And heat. And trouble generally. [/QUOTE]
