My garage is cinder block. I'm installing two outdoor motion sensor
decorated accent lights on each side of my garage door. I'm mounting the
fixture directly to the block, drilling a hole through the block and
running Romex through to the inside of the garage, which will then
continue the run into the breaker panel. When running the Romex through
the cinder block from the fixture on the outside to the inside, I am
planning to insert a piece of conduit or PVC in the drilled hole, then
running Romex through it. Is this the best option to run the wire to panel?
Without seeing it, this all sounds fine, as long as you mount proper
electrical boxes for the lights. I agree to seal it with silicone, which
will keep bugs from getting into the boxes (and maybe mice too).
Romex should be stapled, so I'd take it straight to a wooden rafter, or
you can attach a strip of wood on the wall to fasten the wire. Or just
run it thru conduit where it crosses the block wall, until you get to
If you run it thru metal conduit, be sure to deburr the ends.
Whether actually req'd or not, it just looks so much better...my
understanding was that "exposed" in unfinished space meant still thru
wall, not on the wall surface directly exposed. But, I don't have new
NEC at hand (2011+?) w/ the Art 334(?by recollection) and clear
definitions to refer to directly...
The current cycle is 2014 but there are plenty of places still on the
11 or even 08 or earlier.
The thing that is consistent is that "Exposed to physical damage" is
ambiguous and "extreme damage" is even more ambiguous in the code.
A lot is left to local interpretation and custom. That is particularly
true about Romex in utility spaces in a dwelling. Where I was in
Maryland, above 4' it could just be stapled to running boards. In
Florida they want some kind of raceway but Smurf will do in most
places. Other places want EMT. The wild cards are MC/AC cable and
Smurf. The perception is they are tougher than Romex but the NEC rules
are the same in reference to physical damage.
So, *no* Jbox on which to hang the fixture? How do you plan on
connecting (wiring) the fixture to the ROMEX conductors? Where
do you expect the service loop to be stored -- tucked inside the
What's on the *inside* of the block wall? Will you just have a
piece of ROMEX poking out a hole, draped along the wall/through the
ceiling to the loadcenter?
Define "best". :> Do you care about Code or just want to get the lights
Here, I install boxes *in* the block so there is a place for the
wires to terminate *and* for the fixture to attach. Just like you'd
encounter *in* an interior wall...
According to an electrician, it isn't code, BUT, after more thought, I
agree with you and can't see how it wouldn't be code since the exposed
romex could be penetrated along it's run. Thus, the conduit will protect
it. I will run conduit to be safe.
