Hello all -
I'm the original poster of this topic. Sorry, been busy the
last few days.
My last post asked about [what I now know are properly
called] "fuse reducers".
Got a more serious problem now.
My house has the old 60-amp service with 2 "fuse blocks"
(again, I'm not sure of the proper name for the part)
located above a row of fuses.
The one on the left is marked "main" and the one on the
right is marked "range". The "range" circuit is being used
by my dryer.
After investigating with a multimeter for continuity, I
found that the root cause of my dryer not getting power was
not either fuse in the block, and not specifically the fuse
reducers (although one was worn and pitted).
Of the four contacts in the fuse block, one was marginal,
i.e., not "gripping" the fuse tightly. I believe that when
the block was pressed into the electrical box, this marginal
contact was made worse. The end result is one contact point
between the fuse reducer and the fuse lugs is weak, perhaps
arcing, and sometimes losing contact altogether. No good.
Well, I tried bending the contact lug and the thing broke.
Not the lug, but the fuse block itself!
I've gone to a couple of electrical supply houses in town
(the places where I assume electricians go when they need
parts), and they guys just say, "nope". Not made any more,
they can't get them.
I tried a search on ebay. No go.
I've tried googling, not getting anywhere.
Clearly, I need help or advice from others who know a lot
more than me.
Can anyone provide a source for these old 60-amp parts,
used, salvage, whatever? A name, phone number, URL would be
a BIG help.
Ever tried to super-glue one of these back together? I
assume it's made from Bakelite, it's not plastic. The break
is clean, with some surface area for a grip, but I'm
wondering if it won't just break off in place once I press
it back into the circuit box.
If I can't find another one, or can't repair the one I've
got, guess the only option is to start looking for someone
to upgrade my service to 100amps with circuit breakers. Will
electrical contractors do this, but still leave in place the
old knob-and-tube wiring for the time being? I can't afford
to have the entire house wiring replaced.
