So we are running about 180w of CFL's in a grow box in an attic. We have about 90w each powerstrip and have them plugged into a extension cord which we ran to the garage level. First it was fine then we plugged in a heater then the whole garages electricity went dude and we moved the extension cord inside to a computer room where the same thing happened a few days later. Now none of the eletric will work in any of these rooms. Any tips?!
