Blown outlet help Answered

While working with HV I got a short on the primary side for some reason. I thought "no big deal, just go flip the breaker (it actually flipped my personal 15 amp breaker that's used with my HV projects, and the 20 amp room breaker)." So I go reset the breaker, and now all of the outlets in my workshop work except the outlet I had my projects plugged into. ehhh..... WHAT DO I DO!!!!!!!!


ok,thanks guys, I'll try that. Luckily it's an outlet in an "uncomplete wall," you know, the kind of stuff in a basement closet.

. You may want to install some fast acting fuses somewhere in the line. Circuit breakers are notoriously slow acting and even a fuse quite a bit larger than the CB rating will isolate a dead short faster. Hopefully before you burn up a wire or receptacle (or house).

Problem solved! Turns out that the ONE outlet I was using has it's own circuit breaker with the rest of the circuit breakers in my house, NOT the basement circuit breakers... I was looking at the wall wires, and it appeared to be 10 or 12 gauge wiring, with a max amp rating of 41 or 55, soI don't think burning a wire is going to be a problem.... but whenever I do trip a breaker that's awlays my biggest worries...

you need to take really huge current to fuse a contact that was not the one that took the flash of the short circuit if you did maybe your breakers are slow. breakers have types that determine their speed of reaction on given current. in DIN breakers type C is the maximum i'd put in there. type B is faster so better (but may trip if you have momentary start currents above 4X the rated current). I dont know the levels in american breakers

. If you plan on doing a lot of experimenting, fuses may still be a good idea. Probably overkill, but it will provide some extra protection for the incoming lines.
. It wouldn't be a bad idea to replace one of the breakers or the receptacle with a GFI unit.

. There's a chance you burnt out a wire or possibly a connection. If you have a voltage detector*, you may be able to trace the fault. Maybe not - they have a very short range and if you have thick walls...
. First thing I would check is the receptacle itself. If you have voltage at the terminals, the receptacle is burnt. If it's the kind where you stick the wire into a hole, the internal connection (usually a knife-blade type arrangement) may be burnt.
  • Not a recommendation, just an example.

You probably fried the outlet and the overload there tripped the breakers. Make sure the juice is off, remove the coverplate, unscrew the outlet and pull out of the wall box to inspect it. Either a wire burnt and broke off or oxidized enough to break the circuit. Can you poke around with a circuit tester to see if the just the plug contacts are oxidized? Either way, it is easy enough to change the wall outlet.
