A very knowledgeable co worker of mine claims to have failed a rough inspection because of an MC connector being used in a box that is to be concealed in a wall. I believe it is a JHA vio. Any thoughts?
Thanks Roger and Greg for your replies. It was a plain old side bracketed deep 1900 box with 9 ko's (3 on 3 sides with no internal clamp)used as a switch location (mud ring added) NEC 2005 Art 330 does not mention any vio about MC connectors in walls or concealed locations.

I have heard folks claim that 90-degree MC, or flex, fittings had to be treated as an LB would be treated, and remain accessible.
Personally, I do not share this opinion. I do concede that some such fittings have little covers that make them resemble conduit bodies, but I still do not consider them to be the same as conduit bodies.
As for straight connectors .... I'm not sure it's possible to use them without concealing them. The NEC clearly allows for fishing the material ... and it's been quite a while since I saw a box with internal clamps.
