While working in an older unit, I was helping to track down which fuse
controlled which circuit. The fuses were in a closet, in two separate fuse
boxes. These were the screw in/screw out fuses.

There were several porcelein fuse holders and each contained 2-4 fuses. I
unscrewed one fuse and noticed that the ceiling light in the bedroom went
out. However, when I unscrewed the other fuse in the porcelein fuse holder
(there were two) the same light went out. The same thing happened for the
light in the closet.


Why would two fuses control the same light?


The fuses are wired in series. Strange!

Maybe some know-nothing who wired the place put fuses in BOTH the hot
and neutral leads? That'd put them in series, but without a common
connection between them.

Someone with a voltmeter and a little knowledge could sort things out
pretty quickly.

I have both (heh), what should I do to test this hypothesis?
