General Question About Circuit Breaker Box


My stove stopped working. I checked the electrical panel and made note of the breaker for the range. All looked good. Condo built in 1972. Isn't the circuit switch supposed to go 1/4 to the off position to indicate it was tripped? Mine didn't. The owner suggested turning off that switch then back on and that did the trick. Did they not have that feature back in 1972 (where the switch goes partially towards the off position when tripped)?

It would be nice to know what brand of breaker.

Re: General Question About Circuit Breaker Box


Depending on the brand, the breaker handle will flip completely, halfway, or barely move from the full "on" position.

Since the problem has already been solved, shouldn't you be off painting something?

Good point. I'm going to relay that to the owner. BTW, the stove is a home depot GE cheapie, about 3 years old.

Why is that? Shouldn't you not be wasting bandwidth, which you are?

Likely a 40A circuit. Quite possible to trip that with all burners and oven on.

Were you cooking up a storm?

Re: General Question About Circuit Breaker Box


You can have a 50yo pos stove and it won't trip the breaker.

Does the breaker match the stove requirements? Peak draw is during a self clean. Maybe it's an old breaker, maybe it's the wrong breaker, who knows.

The heating elements are basically bent metal rods. Not that much can go wrong unless they start wearing out, get too hot, and bend down shorting out.

That's pretty hard to miss.

Re: General Question About Circuit Breaker Box


And the other answer - no, not all breakers trip half or a quarter of the way. Depends on the breaker.

Au contraire, son. I made a germane contribution to the subject, which you conveniently ignored.

As for wasting bandwidth, your post history contains a plethora of questions that have nothing to do with your professed trade, while you are typically quite prickly about others who ask advice about painting. Don't make me take the gloves off.

Re: General Question About Circuit Breaker Box


Another possibility is poor connections at the breaker. Either at the conductor terminals, or between the breaker and the buss bars.

If any are loose, or corroded, they'll heat up. And the heat will be picked up by the breakers' thermal bimetal strip.






But what do I know? I've only seen it a million times.

I've always thought they moved a little bit at least, otherwise it could be really difficult to ascertain which breaker tripped. Could it be that when they get old they're less likely to move?

Maybe it's an FPE or Zinsco panel with breakers?

Some move so little it's tough to tell. I don't know why. I've wound up resetting ones that I couldn't really tell they had tripped.

It could be from heat warping a plastic part.

It could be from dust collecting on it.

It could be the simple fact that it's a man-made mechanism, and all such devices are subject to failure (mostly as a result of cost-cutting mass production techniques).

It could be a defective breaker from the git-go for the same reason.

It could have sustained serious damage somewhere in the past and only now the resulting problems are manifesting themselves (think of buying a used car where the previous owner ran the engine for miles without any oil).

It could have been a used (mis-used / abused) breaker was installed by a shady Craigslist wanna-be electrician who was just out for beer and pizza money.

It could be a counterfeit breaker.

For all we know (given your total lack of information provided), it's not a breaker listed or classified for that panel.

If could be Elvis is alive and well, sneaking out of his hiding place and using the stove to make his fried banana sandwiches at night.


Ad nauseum. Ad infinitum.

Re: General Question About Circuit Breaker Box


Here's a email reply I received from the owner. I'm not implying this is the be all answer.

"Jerry the electrician who kept all my machinery running in my printing business said circuit breakers have a surge factor
of 10% over and under on their rating. As they get older they lose the 10% and trigger at a lesser amounts like 6% or 5% over/under the rating. When that starts happening it makes sense to replace them at a convenient time so it doesn't disrupt production (or additionally break down and fail and cause other problems)."

The box was installed in '72 when the condo was built. The sticker says Sylvania. There wasn't any heavy use of the range (all burners and oven on). I knew which switch to turn off and on as they are all labeled.

It appears that simple age may have been the factor as to the switch being tripped. Why the switch didn't move any after being tripped, I don't know. Maybe age related too or that model of box simply doesn't do that.
