No offense to anyone on this thread, but the electrical advice given above is 100% INCORRECT. I never post on these things, but since I'm a licensed electrician, I felt obligated to stop anyone from making a potentially dangerous mistake. I just want my fellow reefers to stay safe.

Your breaker size is determined by the size of the wires in the wall. DO NOT put a larger breaker in because you are tripping the existing one. That could cause the wiring to overheat and start an electrical fire. A breaker trips to protect the wire. The total load on an electrical panel is determined through a series of load calculations, not by adding up the numbers on the breakers. Many times the breakers "add up" to a larger number than the panel rating. I hope that helps.
