What Breaker Is Compatible With Crouse Hinds Panel?

[DerbyDad03]

I need to replace one of these 20A Crouse Hinds breakers with a 15A. This is the best picture
that I have, but I'm pretty sure it's a Type MP.

If I'm not mistaken, CH is now Murray, so I think this is what I need, but I wanted to check first.

The job is at Dad's house, 350 miles away and I'd like to avoid running around shopping
after I get there.

Thanks.

Yes, that is the correct breaker. You could also use a Cutler-Hammer
BR style:

Thanks.

One of those 20A breakers has 14g wire on it, the other has 12g. We're
selling the house, so I'm trying to remove all the obvious in-your-face
red flags, which I why I want to put the 14g wire on a 15A breaker.

(I was fully expecting to see more than one circuit on some of the breakers,
but I was pleasantly surprised that the 14g wire on a 20A breaker was the
only issue - in the panel, at least.)

What is interesting is that the breaker in the picture seems to indicate
No 14-8 AWG. Could the breaker be so old that the NEC allowed a 20A breaker
to be used with 14g wire? Doesn't matter, I'm replacing it it anyway.

That is really just the listing for the termination, not the breaker
itself but I can give you an instance where #14 is perfectly legal on
a 40a breaker ... but I don't want to confuse people.

[DerbyDad03]

Please do. I'm interested. The rest of the "people" can ignore your
post.

Being limited to 15 amps with 14g is based on lighting circuits,
receptacles, etc. If it's a piece of equipment like an AC unit
that has it's own over-current protection, then a larger breaker
consistent with the eqpt's rating plate is allowed. That is so
it won't trip on start-up. So, you could have a 20A breaker on
14g cable.

Also possible is if the wire making up the cable is of higher
temperature rating than that of ordinary T,TW, etc., for which the basic
rule we all know and love holds. _Probably_ not the case here, but it
is another place where consultation of the actual ampacity tables for
the specific conductor rather than the rule-of-thumb may lead to a
different result.

What has legal to do with anything?

What he said ;-)

When dealing with motor circuits the typical inverse time breaker can
be 250% of the ampacity of the conductor per 310.15 if the motor has
internal overload protection.
