Ok, So this has been puzzling me for some time now. Our house lights in one section of one of our dimmer racks are flickering every so often. Up until today i thought it was caused by humidity. But today when they flickered i went up to the Racks and there was a RH of 30%, Usually the flickering hadn't happend till twice that amount. What else could cause flickering in a set of dimmers, Dims and Non-Dims alike? There are 4 of them in a T pattern in the Rack, the three on one level and the center one on the level below them.
