no 18.9 on a 20 amp will trip the breaker all the time (like morning start-ups when lights come on), you gotta eliminate something, or add another breaker like gagrown says, thats pushing it.
4x5 Reviewed by 4x5 on . Electrical Question Hi everyone:stoned: I have an electrical question for you to ponder. My grow room has its own 20amp service. Im thinking about adding more lights which will push my total demand to exactly 18.9 amps. Is this a safe enought margin? I dont want to burn my house down. That would be a bad thing. Thanks for your help :rasta: Rating: 5
