    25 amp "resettable fuse"?

    I'm looking for a 25amp "resettable fuse" just like the lil poppers but rated for 25 amps.
    Had anyone made one from like a breaker or something?
    Do they sell such a thing?

    Im trying to track down a short or something in a carrier RTU that blew the 120v 25 amp fuse btw.

    Why don't you just ring the units power to ground then start unplugging electric components till it stops ringing?
    Its not that hard to trace out a grounded wire or motor.

    There are surface mount circuit breakers, these were mounted with two metal tabs and used by Hussmann in their condensing units.

    I think this is what you're looking for. Couldn't find the 25 but they are in the grainger catalog.
