Re: wiring a cyclone
I am in no way an electrician. But I do know that the two circuits are totally different in nature. If you break them apart and answer them separately then you'd get to the root. But I am going to add in a question that Clint will need to get answered too.
Just looking at the Cyclone motor. In my case, this is a Leeson 5hp motor with an amp rating on the unit of 21amps continuous duty. I have spoken with one of the inspectors from ESA over the phone and got totally lost. The break down went something like this.
On a direct hookup of a motor, you need to allow for a larger startup pull, so the WIRE needs to be rated at 125% of the current load of the motor. So on my motor, that means it can carry 26.25amps. So 10g wire needed to be used. But then he went on to say that the breaker needs to be rated at 175% of the current load, that works out to 36.5amps, so I should use a 40amp breaker on the circuit. This is due to you are going to turn on the motor (cyclone) and have it running continuous for hours at a time.
If there was consistency with this I would accept it, but the ESA inspector who came for my rough in, said that I should be using only a 30amp breaker as the 175% doesn't apply.
Do I need to ask a 3rd inspector and take majority rule? or just go with the inspector who is actually signing off on my install?
People are like a box of chocolates. It's hard to tell initially which ones are nuts.
