Unorthodox Use of Extension Ring - ECN Electrical Forums

Quote

I found this "junction box" on a job recently. Among the items to note:

-An extension ring is used in place of a box;
-the 'conduit' is not continuous with wherever the wires go out the back of the ring;
-the EMT is installed without using a connector;
-unprotected wires enter the box; and,
-no attempt has been made to anchor any of the raceways.

I'm sure this guy (it's always a guy...women know better) does something else well, and should stick with it before he kills himself or his family.

That looks like exterior house siding. I don't think this install will be any good for outdoor weather. Knocking a big gaping hole in the siding is also a bad move; rain water can get inside the house and cause rot and such.

Unless this is a listed box, he has modified the back by cutting it out. Notice the screws that secure the box to what may be another box behind it.

Has anyone seen a listed 1900 with this type of cutout?

This IS a listed box. It's used as an extension box on top of a rework (or gem) box.

...listed for interior use only, of course.

A few more comments on my pic:

- The box is mounted on what once was an exterior wall, but is now enclosed by an addition to the original building; and,

- The box / extension ring is in fact a listed, factory made product. It is intended to attach to a single-gang box, be it a "handy box," or cut-in (old work) box. Finally,

- While not clear in the pic, the 'ring' is NOT attached to a box behind it; it is attached directly to the building. While there is other raceway on the other side of the wall, it does not directly connect to this ring.

I am truly amazed as to how many violations can be put in such a small area.
