I'd expect the 120V loads to be divided between the 2 legs. That's the
way it is in every house or apartment I know about (other than a
couple of older ones that don't have 240V service).
How many for each light?
Switching the neutral works but is considered unsafe. It means that a
wire going to the light will be hot even when the light is off. There
is then the possibility of someone thinking it's safe to work on.
Homer, might your last name be Simpsos?
Your utterances on this thread represent an exellent example of what the
legal profession uses, ie language which tends to supress information.
How about telling us what kind of "tester" you're using and what you are
connecting its leads to when you get those indications.
Again, what kind of voltmeter, electromechanical movement or digital?
And what are you connecting its leads to when you make those measurements?
When measured in reference to what? each other, neutral, ground or your
Do you understand how capacitive coupling of AC signals can cause
"phantom voltages" to be measured by sensitive intruments. (Actually,
"phantom" isn't really a good descriptive term, there IS a voltage
present which does get measured, there just isn't more than a few
hundred microamps of current delivering capability there, which for
practical purposes might as well be zero.)
I knew we'd eventually get back to your gonads. <G>
Lim time again:
There once was a man from Woonsocket,
Who stuck his big dick in a socket.
His wife was a bitch,
And flipped on the switch,
And his balls both took off like a rocket.
I'm really having a hard time figuring out how a DPST switch in the
original location could be wired to make a "three way" circuit work right,
Do you have the knowledge and ability to use the ohmmeter function on a
meter to measure what that switch does when it's disconnected from all
wiring? If so, do so. I'm betting you'll find it is really a SPDT, with
maybe the fourth terminal for "ground".
Getting serious, I think you'll just need to replace that old switch
with a SPDT ("three way") switch with the hot wire from Pair A connected
to the "arm" terminal and the two wires from pair B connected to the two
"contact" teminals. As far as the second wire in Pair A goes, you can
probably cap it off and leave it unconnected.
My advice is warranted for exactly what you're paying for it, as I'm not
there to verify what you've explained thus far, and have no way of
knowing whether for example the "second wire in Pair A" might actually
be a ground lead.
It "sounds like" you have a 4-way switch that wasn't wired properly in the
"Proper" in this context means that you have the "return" of a circuit
that's not in the same cable or conduit as the supply.
When you wire 3-way or 4-way switces with "romex" you MUST use 3 wire (or
more) cable. (That's RED, BLACK, and WHITE.)
In a switch loop to a three way switch, the white wire is HOT all the time
and the 3-way switch connects the white wire to either the red or the black
If you have two (or more) switches controlling the same fixture and there
aren't any RED wires in the junction boxes the guy who wired it was too lazy
to get the proper 3 conductor cable.
After reading through this thread, I also suggest bringing in a
professional. What we are seeing is an homeowner, who while intelligent is
not well informed or experienced about residential electrical systems and is
not confronted by a not so common wiring situation that the average
homeowner would have very little or no experience or knowledge of. It is
also a little too iffy for anyone who can't really see everything to makes
sure they have covered all the possible situations you might confront and
therefore you could be facing a serious hazard. Time to call the
