Oh, also, the wiring looks to be 12 or 14 ga (cloth covered, older
wire so
it's hard to tell), and the fuses are all 30A. I'm assuming I should
mention this to the owner and mention that he should get the correct
sized
fuses in?

Anyone have the thought that one of the fuses may have been the "main"
and the other fuse the "circuit"?

Mains are not screw in. They are pull out type.


Not necessarily, if the service was only 30 amp, it was common to have plug
fuses



I have the dwg I made on site in front of me now. I'll see what I can do
with ASCII art - 0 indicates a screw in fuse, X and empty space in the
fuse block, and the numbers are my reference numbers:


1 0 0 5

2 0 0 6



3 0 0 7

X 0 8

4 0



0 9

0 10


Not as good as I'd like, but it will do. Pairs 1, 2, then 3, 4, and 5, 6,
then 7, 8 and finally 9, 10 are in their own, separate, fuse block. All
but 9, 10 are porcelein blocks with space for two or 3 fuses. The one with
three (3, 4 pair) only has two in it. 9, 10 has a metal box, but still
with screw in fuses. I know that 1, 2 and 5, 6 both turn off separate
ceiling lights, but each one of the pairs turns off the same light. It
does sound as if the neutral is fused. I don't have any notes on whether
the other pairs behave similarily, but could check. It's a small 1 bedroom
unit in an older building in San Francisco, CA.
