Hi, I submitted the following question to Mike Holt's forum but it got
because of violation of "several sections" of the code. Could anyone
site the sections of the NEC that I'm in violation of?
I failed to mention that the penetration thru the basement wall is
sleeved and uses special seals to make it water tight.
Any help would be appreciated. I'm an owner/builder. I passed the
that the county required in order for me to do my own work, but I'm
fuzzy on this one.

I think the problem is the buried LB. Should be above grade with
another one inside and then pipe down the wall inside to the load
center. Don't know code reference off the top of my head; actually
remember this from one of those saturday morning remodeling shows.
(wow, I actually got useful information from one of those.)
Ahhh. here we go. NEC 2008 314.29
Boxes, conduiit bodies, and handhole enclosures shall be installed so
that the wiring contained in them can be rendered accessable without
removing any part of the building or, in underground circuits, without
excavating sidewalks, paving, earth, or other substance that is to be
used to establish the finished grade.
Exception: Listed boxes and handhole enclosures shall be permitted
where covered by gravel, light aggregate, or non-cohesive granulated
soil if their location is effectively identified and accessable for
So basically what that is telling me is that you need to prove that
that LB is listed to be buried, and that you can never build anything
above the location, ever ever ever.
That doesn't address the issue of actually pulling wire through it. I
dunno how you're going to accomplish that :/
Thanks N8N for taking the time.
I've never pulled thru conduit before so I don't know what's
feasible. Would it be hard to pull even if I had access to the LB
I wonder what other of the "several" sections of code I'm violating.
I went thru the fill calculations and I'm more than OK.
Don't let N8N do all the work, anyone else chime in.
*Start digging. An LB condulet fitting is usually not made for pulling
through. The original installer should have used a sweep elbow instead.
You can try pushing the wire inside while a couple of guys outside pull at
the same time, but SE cable can be pretty stiff. If you do manage to pull
it out and feel confident to get new wire in, I suggest that you use
individual compact copper conductors which will be smaller and softer. Have
the smallest conductor lead out about a foot or more with the other two
taped close behind. It will be easier to get the one conductor through
initially and then you can keep pulling it until the other two emerge. It
will be very time consuming as someone will need to push at the same time as
others are pulling. There is a risk of damaging the insulation on the
conductors as they make their way around the condulet.
