    Hot Water Heater Circuit Break
    What size circuit breaker should be used to wire a 40 gal electric hot water heater? I have been told a double 20 is OK and others say it's not.

    How many Amps or Watts does the WH draw? Should be on the machine somewhere...

    I'm not real sure, I'm at work right now so I can't look. I know the one in my mobile home was hooked to a double 20. My dad is wiring a small house for me and he said the double 20 would be OK, but I wanted to double check because I didn't want to burn up the elements or anything.

    To answer the question we must have more information. Not all water heaters are created equal. Give us the wattage, make/model, and any other information you can.
