I removed two light fixtures in a room. One worked with two three way
switches and the other one was on a separate single switch. I have
installed one new light in the room and was able to run the three way
wiring to the new light. My question is I now have the wire from the
other single pull switch---Am I able to at the new light fixture
attach wiring from the three way, the wiring from the single pull to
the new fixture by nutting all whites and all blacks at the new light
Hope this is clear, lol.
You want all three switches to operate the single fixture? This will
require a 4-way switch, and you definitely can not do it the way you
suggest. As to whether it is feasible some other way, you'd need to
provide a more detailed schematic of the wire runs and boxes involved.
Anyway, here's a WAG as to what you had and have (where IP is incoming
power and --2-- is a 2-conductor (plus ground) cable).
IP --2-- SW1 (3-way) --3-- SW2 (3-way) --2-- Fixture 1
IP --2-- SW3 (2-way) --2-- Fixture 2
IP --2-- SW1 (3-way) --3-- SW2 (3-way) --2-- Abandoned Fixture
IP --2-- SW3 (2-way) --2-- Fixture --------2------|
If you abandon one of the incoming power cables, then the only way to
make all three switches work would be to have all the boxes connected
with 3-conductor cable.
Now, if the incoming power goes to SW3 first, and power goes from
there to SW1 , and that box has no outgoing power feeds, then you can
do what you want. You can wire it like this:
SW1 (4-way) --2-- SW2 (3-way) --1-- Abandoned Fixture
IP --2-- SW3 (3-way) --1-- Fixture --------1------|
Where I have only indicated the number of conductors that you would be
using in each cable, some of the conductors would be abandonded. Note
that --1-- is the neutral going to the fixture, and I don't know if it
is allowed to run the neutral separately from the switched hots like
this. Can anyone comment?
Did not jot down which wires are going where when removing the fixtures?
No one can tell for sure how it's wired without looking at it.
If you lost track, I'd test with multi-meter and sort them out.
Your question is a bit sparse on detail, but I am reasonably sure you cannot
do it. You would almost certainly need 4wire from the light to the switch,
and you probably only have 3wire.
(Even if you had 4wire, you still couldn't do it unless there was also 4wire
going to the light from the 3 way switches. Wiring wise, all the switches
have to be in a chain, connected with 4wire.)
