recently installed 4 1500 watt lutron dimmers next to a 120 208 panel. the 4 lighting legs originally terminated at the breakers and they used to be operated by a contactor board located on the opposite wall. the contactor board is shut down ( breaker is off) because the owner just wanted to dim the dining area lights manually from the electrical room.
problem is, the breakers that are now feeding the dimmer switches are buzzing at half tilt and even more as the lights get dimmer. never been any previous buzzing prior to dimmers or when lights are at full brightness. only when dimming
is this perhaps a neutral issue? between phases? or just a compatability issue with the breaker and dimmer type.
also the wattage is well within the 80% range of the dimmers
