Since you guys like talking about electrical so
much, i've got a question. I do some volunteer
work on an old building built in the 30's. Main
power comes into the building to a main fused
disconnect, then goes to the meter, then from the
meter main lines run through a trough terminating
at the main fuse panel. There is no ground wire.
Between the meter and the fuse panel a lot of
lines tap off the main, to feed heat, water pump,
blower motors, and other circuits. All of them go
through their own fused disconnect before going to
thier destination. Each disconnect has two fuses,
one for the hot and one for the neutral.My
question is, why are all of the neutral circuits
fused? Is this because of the lack of a seperate
ground? all of the cable is either bx or metal
conduit. Yesterday a fuse blew in one of the
circuits. (someone overloaded it, we know why it
blew). We had no spare fuses on hand, so i took
the fuse off of the neutral circuit, connected the
neutrals directly together, put the fuse over on
the black hot side and we were back in business.
Can I leave it like this, or do i need to put a
fuse back in the neutral?
