15A vs 20A circuit for American Standard Whirlpool
10/13/03 10:23 AM Edit Reply



I am planning an install of an American Standard Williamsburg Elite Whirlpool and the directions specifically say that I should install a 15A dedicated GFI circuit. Are there any problems with my installing a 20A circuit instead? I have lots of 12 gauge wiring and also have an extra 20A breaker...but don't want to do this if there is a reason that the motor should be on a circuit that trips at 15A. Any insight would be appreciated!

I believe you already answered your own question.

My question would be: "Do you mind climbing into a tubfull of water knowing that the electrical attached to it may be suspect?"

It takes less than 1/10th of an ampere of current to stop a human heart. Still want to go with the 20A circuit breaker? You can run the #12 if you like but buy the best GFCI you can buy! Gambling isn't any fun if winning means you don't die.

Go ahead and use the 12-gauge wire, but spend the extra $3.95 on a 15-amp breaker.

It's possible the motor has its own protection and the circuit breaker recommendation is nothing more than a source minimal requirement. I would ask the motor manufacturer.
