If I understand you plan on using a larger breaker on the original wires. NO NO NO The breaker is to protect the wires & must be no larger then the rating of the wire. If I misunderstand "Opps sorry". If you can determine the size & type, copper or Alum. of the wires you can decide if you can use a larger breaker but the odds of the wire being larger then needed are pretty small. Peace Jack
GoFish104 Reviewed by GoFish104 on . Amp question for you electric pros??? So I came across a power cost chart and it mentioned that you shouldn't draw more than 75% of the rated amps of the circuit. So here is my question- my grow space has a 16 amp circuit. I have 130w of cfl which draws about 1.5 amps. A blower that draws 1.2 amps at full power. And a 1k HPS lamp that draws 9 amps. A couple smaller fans that probably draw another amp. So that's about 12-13 amps that I will be drawn. Is drawing 13 amps from a 16 amp circuit too risky? Anyone know an Rating: 5
