Im running roughly 120 amps to my main panel and its rated fer 200 but some how the main breaker keeps tripping iv staggered the lights to fire 4 lights every 8min so as not to overload the main the only thing I can think of is the electrical room which houses the ballast and timers and main panel reaches temperatures of what seems to be 120 f I switched the main breaker out just because I had an extra and it lasted maybe two days before it flipped off (at the start of the cycle) Im no electrician just have a lill hands on exp. So please any help would be greatly appreciated. Sent from my SPH-L710 using Grasscity Forum mobile app
