Sorry in advance for what may seem like rudimentary questions...but
just want to make sure i am doing this right.
I am tapping into an existing outlet to add a new outlet about 6 ft
away. The location is around a corner wall. So in my drawing below,
o1 is the original outlet, x looks like a junction area in the wall
that provides the power. o2 is where i want my new outlet to be
My plan is to splice the wires from X and run to o2 using #12 or #14
cables. I wanted to cover this up using wire molding so it looks neat.
My question is, how do you install these things. Do you run the wire
through them first or do you install the wire molding first then run
the wire through them? The wire wolding i have seems to have a long
metal sheet as the back plate to which the molding itself is attached.
That metal sheet can slide in our out (left or right), but i don't
think you can snap the moulding on to that...implying that i have to
'feed' the wire through the molding and therefore must run the wire
through first before attaching these molding.
I did a google and could not find much on the proper way to install
these things and the instructions are not very clear in terms of what
you do with the wire and when.
thanks for any advice.
The last time I did this, the channel was a plastic thing. It stuck to
the wall with adhesive backing on the plastic channel. I then laid the
wire inside the channel, and snapped the cover piece on. The fittings
for the boxes (3, in your case) go on first. Cut the channel to fit.
There is a piece to go around the corner, as well. All the stuff at
Lowe's or Home Depot. I needed to put power in a closet for a computer
printer, wireless print server, and document shredder. Maybe an hour's
work, not counting time to get the materials. Some years ago, I did
some stuff in my garage for an outlet for a trash compactor. That one
was a metal channel. Same deal, but slightly different fitting system.
You can use "500" steel wiremold which mounts to the wall either by back
straps or over the mold two hole straps. You first remove the existing
outlet and install an extension box to bring the existing outlet to the
surface, then you attach your "500" wiremold and whatever fittings,
internal, external elbows, etc., then you install your outlet box, slide
your new conductors into the molding and connect to the existing outlet
Thanks all. i finished this...it took me quite a long time since it
is the first time i did something like this.
It turns out that the existing box that i wanted to tap into had two
hot wires coming out of the same cable, but from two different circuit.
that threw me a bit. I also initially tried shoving the entire cable
in their (#12). When that wouldn't fit, i stripped the sheeting and
ran just the individual wires (as John mentioned). This still took me
some time as the #12 wires are really tough to handle. the don't like
to fold too easily. I wanted to use #12 because it seemed to match the
existing wire size (even though the existing wires were very old) and
because the circuit was on a 20 amp breaker. This outlet is going to
be used by a surge protector for my computer, monitor, pinter, cable
