Hi everyone,

My 7 or 8 year old pool heater breaker is outside in a panel. Summer use only. We turn the breaker on and off to control the heater. Maybe 15 times a year.

220 volts, I think it's 40 amps.

Today the heater would not turn on. After I flipped the breaker a dozen times it kicked in.

Easy enough to replace the breaker, anything else I should check first?

BTW a few years ago the breaker would flip closed all by itself. The panel is next to the vibrating heater - HEAT PUMP. You guiuys told me to check the connections to the breaker and sure enough they were quite loose. I will check that first.

Question is, how long do breakers last if you flip them on and off 15 times a year?

Thanks

Seven or 8 years...


(Kidding. Sorry, I just couldn't resist...)



Maybe an electrician will chime in, but seriously, it's a mechanical switch, subject to heat/cold/moisture/etc. It's unreasonable to think it will last forever, which I don't sense is your expectation. Too many external variables, coupled with the manufacturer's planned B10 life to say "X-years" is my guess. smile

Depends on load at the time of switching.

If under heavy load it may only last a year or so.

It may help to turn down thermostat before turning off breaker.

8 years may be normal for that application.

Life depends on whether or not the breaker is "switch rated"

It's hard to see, in the small print, but there usually is
a small 'swd' in the description on the breaker, IF it is switch rated.

So, yes, it can be used as a switch, but for how long is speculative.

I know one application where the breakers are used as switches
every day, primarily for lights. most are 25-30 years old.

I'll get what Lowe's has as long as it fits. If they have a switched one I'll get that.

Thanks for the info

More info. The panel is a Seimans, the bad breaker is a Square D.

Just found that the panel lists all breakers that can be used.

Under "Double" it lists Cutler Hammer BR. Square D HOM. I will look for that.
