Everything's in a detached garage and all hooked up to the 2 breakers. Pretty much as the tent stuff (light, fans, heater) are plugged into a power strip in 1 outlet and the rez pump, rez heater (100w) and dehumidifier (not plugged in) and stir pump are plugged into a power strip on the other side of the garage with an extension cord. But all of this stuff has been running, with the dehumidifier, since probably October with no problems. Maybe a bad power strip? Don't know why it's flipping the breaker instead of the power strips
