Questions & Answers

How many circuits and wht size breakers

Asked by: Sparky
Regardless of who is right or wrong...if RHEEM says it requires 4 x 40 amp double pole breakers that is what you use....otherwise there goes your warranty....or worse! What little I know of electrical tells me the math is right....I am not taking chances just to pretend I know more than the next guy....or save a few bucks!

My house has 1300 sq feet and we are a family of 3. Will this heater work for my house?

My breaker is 30 amps now can I change it to 60 amps? And this one work better 11kw
Asked by: Eddy
Circuit breakers are sized to wire and other devices that they protect. You should never change a circuit breaker to a larger size before ensuring that the downstream wire and devices are sized to match the circuit breaker. It is likely that the wire and devices in place are only rated for the amperage of the existing breaker and you will not be able to change only the breaker.

Will this work in a 1 bathroom tub an shower an on a kitchen sink? In southeast South Carolina thanks
Asked by: Mike
I’m in NJ and can run the shower and the sink at the same time up to 140 degrees all winter. It should supply hot water to at least two things at once. You may need to run water for a bath by itself without any hot water on anywhere else.
