a quick note that might help here. I've noticed that we often have to compair watts vs amp loads on our circuts. Try this out. There is a simple way to convert this. I use the P.I.E method at work all the time. So P (watts) = I (amps) x E (volts). so for an example I have a 500 watt heater and I want to know the amp draw at 110 volt supply
500 = (?) x 110. A little math here shows that by dividing my watts by the volts I can find my amp draw and in this case it is 4.54 amps.
Maybe this will help some of us when figuring out wiring.
