Hook-up for elec. water heater


I would like to place a small 12 gal h20 heater (Whrilpool) in the garage.
It will be about 40 feet from my sub-panel. Can I use a 20 amp breaker with 12/2 (dedicated circuit) or do I need a 30 amp breaker with 10/2 wire?
I'm thinking the instructions would most likely tell me but I haven't bought the heater yet as I'm still in the process of building and wiring the garage.
Thanks for any help.

You won't know until you get the heater, or at least the specs.

A small 12gal might very well be only a 20A/120v circuit. Can you look up the specs online?

Hey Speedy, all I know at this time is that it is 120v.

An educated guess would be that a 20A circuit is fine. Most of those smaller 120v units have 1500 watt elements.

I have a 10 Gal. GE water heater I purchased at Home Depot. It has a 2000w element and requires a 30amp circuit.

yes, it cant hurt to go with #10, even if it only requires #12 the larger size is there in case you ever want to upgrade. it would be a smart choice to install the #10 wiring now.

As per Stubbie, "Don't forget the disconnect issue......"

I don't understand what you mean, Stubbie.
