During fade (100% to 0%), amperage seems to increase on one controller, tripping the breaker. It is the ONLY controller plugged into the outlet, connected to a 15 amp breaker on a sub-panel. Everything has been working perfectly up until tonight. When this occurs, as the fade progresses, the sub-panel begins to 'hum' louder as the fade gets dimmer, until breaker trips. No hum when controller in question is turned off; other 6 working as intended. Would upgrading to a 20 amp breaker help this issue? Is it perhaps a weather related issue? We are experiencing the coldest temps of this year, 0-10 degrees F.
Note: Using incandescent mini lights, strands of 100. 200 amp house service; 50 amp sub-panel.
Any Help??
