The previous poster was not talking about installing a fan, but
replacing the speed switch. Yes there is only one wire to supply
power from the house to the fan. But in many fans, there is a speed
switch that has one wire that bring electricity in and three that go
out. They go to three different windings (coils) in the fan motor
itself.

okay, in that case, it make sense. So between the supply and three
output wires to the fan motor, is the device called a rheostat or not?
And if not what is it called?


never mind. if you have one of those that connects to different windings
on the motor, I suppose that's just a switch. duh.

And how exactly do you do that? I've also assembled my share of
computers and what you've typed makes no sense.

It makes perfect sense. He is talking about the house receptacle the

okay that makes a little more sense. I was thinking he was refering to an
outlet on the computer and the times I considered rewiring an ATX plug for
a non-standard MB. I still don't see how having a live LAN cable can give
you shock unless it was coax instead of twisted pair.


Yes, I didn't explain that well.

The outlet in the wall was wired so that the normal hot was neutral
and vice versa. The circuit was run in thinwall electrical conduit
with no separate ground wire (the EMT was serving as ground) IIRC.
(It's been a while.)

The metal chassis of the computer should have been at ground. But it
was hot. The computer ran fine, all it cares about is 110 VAC.

The LAN cable was twin-ax, two connectors covered by a coaxial shield,
with nice big metal end connectors. So the shield and connector at
this PC was hot. The next PC on the network was at proper ground, so
its shield and connector were at ground. The two LAN cables were
hooked together in the middle with a double female barrel connector,
so when I connected them I had a hot metal connector in my left hand
and a grounded one in my right hand, and got that old familiar tingle.

Had they been power wires I would have tested with a meter first, but
who ever thinks of a network line carrying power?
