im sure a person w elect knowledge will know better but -you could plug it in and see-but really its when something like a furnace pops on or u run a microwave or even toaster ovens draw alot that causes the trip. So you may be fine at first then say ur blow drying ur hair or dishwashing. Ok bro goodluck wit it. I think its like how many amps ur drawing or something -wish i could help more.

On a circuit with a 30amp breaker you could run a thousand watt light or heater. I dont think you could do that on a 20 amp breaker or should try. Even if you have a 20amp breaker you should be okay with a 600 watt light. Its the additional load on that circuit that you need to add up, do you have fans, pumps, other lights etc? You could add a fan to the 600 though.

Can you plug everything into a surge protector?

Watts = volts x amperes. So if you’re on a 110 volt circuit, 20 amperes is equivalent to ~2200 watts. Switch off your circuit breakers one at a time until you find the one controlling the outlet you’ll be using, Switch it off, leave all the rest on, and check the house inside and out for other outlets, ceiling lights, etc. that are on the same breaker’s circuit (make sure all wall switches are on when you do the check.) Keep other stuff off your grow circuit if possible, use baby protectors on the other outlets if necessary! Peace, John
