Locating your shorts

Elizabeth, yes, basicly a "short", I means bare wires
(or wire and metal conduit) touching. Hopefully you
wouldn't have put both wires on the same side of the
outlet :-). If the insulation is very old and brittle,
just moving it around could have cuased it to crack
and expose bare wire, which may then touch the conduit
and cause the breaker to trip. Inspect the insulation
carefully for cracks. Look for any blackened
or melted looking places. If the wire is pretty bad,
you may need to replace it (not too bad a job when you
have conduit). Try leaving the receptacle off, cap
the bare wire ends, and turn the breaker back on,
if the breaker still trips, the short is probably
just inside the conduit; you'll need pull in new wire.
To verify this, you can go up the line to the receptacle that
feeds the problem outlet and disconnect the wire going
to the bad outlet, then test again, the breaker should
not trip. The "gotcha" here is that disturbing the
wiring at the other receptacle could cause
a similar problem.
