I had a rocky inspection on
an outside outlet. It's at the end of a 12ft. 3/4" schedule 80 conduit which is suspended under a deck above a pond. The outlets are only 5in. above the surface of the water. There were numerable code violations which I knew about and some I didn't. I inherited the mess from a previous owner. I'm basically re-doing the whole business. What I found was a 14/3 NM cable running through a small (1/2") hole in the exterior wall into the conduit, which abutted the exterior wall without a fitting or seal of any kind. That can't be the intent of the code - the cable is unprotected through the wall and the conduit is not protected against the infiltration of moisture, dirt, bugs, etc.
The conduit runs 12 feet to the junction box without any
support. I can only ascribe the situation to negligence and heedlessness - no one
could think this is satisfactory work.
I think the conduit should go through the wall. Since
the inspector ok'ed NM cable in a conduit not underground, I don't need a change-up junction box inside the wall. The cable should exit the conduit through a bushing, and should probably be clamped
between inside and outside.
The conduit should be mortared (outside) and oaulked (inside) into place,
and supported every 6-8 feet with a clamp. I'm going to move the outlets so they're at least 12in. above grade, and several feet away from the pond and muddy shore. I'm
not familiar with code here, but I just know what
ought to be good. What else
do I need to do?
