I need to extend an 110V outdoor outlet box for 10 feet horizontally and 8
feet vertically along the outside of my house. This is for security
lighting. The outside of the house is stucco. The inside is 16" studs and
Can I use wiremold or do I need to use conduit, which would be unsightly.
Any other suggestions?
I dont think they sell a waterproof wiremold, but it never hurts to
ask a supplier. I think I once saw a website too. Maybe wiremold.com
Why is conduit unsightly. It's just a half inch pipe. Use plastic or
steel, your choice. Then paint it to match the house. You might be
able to put the horizontal run under the overhang, or on the
foundation rught below the siding, and maybe cover it with trim.
Can you come right out of the foundation from the basement? Run it to
your breaker box. Then you only have the vertical run to see.
Another option would be to run the wiremold INSIDE the house and just
exit the wall right where you want the fixture. It's either that, or
rip the house apart. Your choice !!!
I just looked, here's the wiremold website.
Or just use wiremold.com (thats how I got there).
*Cut a 10' long 5" wide channel in the inside wallboard and drill out each
stud. Wallboard is easier to patch and paint. Wiremold is not rated for
outdoor use, though I have seen it used outdoors. It rusts.
Run conduit underground 10' and then mount a weatherproof box down low.
Come out of the back of the box into the wall and fish your wire up the
You could probably get away with using PVC wire ducting if you use wire that is
insulated for wet locations and it is installed in a fashion that will not allow
to jeopardize the structure, junction boxes, or fixtures.
Why not hide the conduit in a wood or PVC molding of some sort while using
standard bell box extensions and fixture boxes?
Make sure to clear everything with a local inspector. They don't mind you
Is there a receptacle box inside the wall, in close proximity of where
the exterior box needs to go?
Tap a wire in the inside an go through the wall from the inside with a
long bit. Pull a wire and fix minor damage to the wall. Touch up
Run electrical conduit under the weep screed at the bottom of the
stucco, then go vertical. Paint it.
Not an electrician, just thinking out loud...
I didn't think anything was uglier than wiremold. If it has to be done
externally, I'd do it in EMT with rain-tite fittings, but I would first look
to see if there isn't an outlet on an interior wall near the location where
you want the fixture. If there is, you can usually tap back to back from it.
In security 101 class, they tell you to not put security lighting ON the
building, since it creates a dark spot underneath for people to hide.
Security lighting should be away from the building, pointing AT it. I'd
bury the wire in the sod, using suitable burial-rated cable or conduit,
and put it on a decorative pole. Add arms for flower pots or bird
feeders or whatever to make the pole look less menacing. You didn't
mention running a switch leg, so I take it this light will be on a
sensor and always hot?
To answer your question about Wiremold, no, they don't make anything
suitable for exterior use. I can say that with confidence since I have
their complete catalog (from last year). Lots of interior "systems" but
nothing for outdoors.
The fashion in killing has an insouciant, flirty style this spring,
with the flaunting of well-defined muscle, wrapped in flags.
