Your wireing has issues. Someone probably put a 30 amp breaker on wireing to small to handle the load. Homes generally do not have 10 guage wire unless it is a 220v circuit. Anything less than 10 guage will overheat and trip the breaker with 2 1000w hps. 2 1000w lights will pull just over 18 amps. Thats too much for a 20 amp breaker and most likely your wire overheats because it is too small and trips the 30 amp.I just had 20 under 2 lights. Started with 1000 watt, had to switch to 600 cuz my designated 30 amp breaker kept tripping. So I had 10 under 600 watts in a sealed room with CO2. temps were always 75-78 lights on. I used to have 6000 watts for 36 plants. Now 1200 for 20.
It turned out to be an awesome grow. Wish I could have left the 2x1000 hps running. But my electric bill was pretty managable.
