Post by DerbyDad03I put a light fixture at each end of the attic with a switch in the middle.
The Romex is stapled to the face of the ridge board where it extends below
the rafters. The switch is attached to the ridge board between 2 rafters
and is reachable as soon as you climb the stairs enough that your upper
body is in the attic.
Since the Romex never crosses any open space, I assume it's alright the way
it is.
Thoughts?
If I understand your description it sounds legal to me.
320.15 Exposed Work.
Exposed runs of cable, except as provided in 300.11(A), shall closely
follow the surface of the building finish or of running boards.
Exposed runs shall also be permitted to be installed on the underside
of joists where supported at each joist and located so as not to be
subject to physical damage.
As pointed out previously, it's section 320.23 that specifically addresses
attics and from my interpretation, it appears to say otherwise. Again,
I don't see anything wrong with it from a safety standpoint, I'd
do it myself that way, but it doesn't appear to me to meet the requirements of 320.23.
Perhaps you are not picturing what I have correctly.
The Romex is stapled to the ridge board. It doesn't run across the rafters.
The rafters are a good inch above the Romex. In other words, it closely
follows a running board - the ridge board - as required/allowed by 320.15.
320.15 doesn't specifically address attics. 320.23 does and it says that
any cable run across the face of joists, rafter or studs in an attic
has to be "protected by a guard strip" at least as high as the cable, unless
it's over 7 ft above the floor of the attic. It doesn't draw a distinction
between parallel or perpendicular. If I understand it correctly,
you have it stapled to the bottom of the ridgeboard. While the code
doesn't specifically say ridge board, it sounds like it would fall into
the same category. They want the cable either on the side of the joist, stud,
rafter, or if it's on the face, then protected by something at least as high as it is. At least that is my understanding.
Again, I don't see anything wrong with what you did from a safety
standpoint. I'm just citing what the code says. If they say you can't
run a romex up the bottom of a rafter without a guard strip,
unless it's 7 ft above the floor, then I would think the same applies to your ridgeboard location.
