    MC Cable Used Outdoors

    Can anyone tell me if the attached picture looks code compliant. This is at a NJ Shore resort town 300ft from the beach. The installer states that it is code compliant. This work was completed after the building was constructed. It uses MC cable and normal connectors. NEC 2014 330.10(A)(3) allows the use of MC cable outdoors, but 330.10(A)(11) states if used in wet locations must have a corrosion resistant jacket over the metal jacket. Im confident the installer used landscapers and not electricians for the installation. There were (3) photocells in the white boxes for conrol of exterior lighting. the residents wanted the lights on a timer is why the installation was changed.

    Not compliant: no outer jacket, wrong connectors, and not secured properly.

      Proper support of cable would be an issue even if allowed there, which I don't think it is. I wouldn't have done it even if it were, which is why I'm not 100% sure it isn't, but I know which way I'm betting.

      EDIT: And that's besides the fact that I'd be ashamed to leave an ugly mess like that behind and call it a finished job.

        Not code compliant for several reasons. A corrosion resistant jacket is an option for wet locations.
        You may well be the sharpest tool in the box, but in the end you are still a tool.

          The MC cable needs to be connected to a box or conduit body.

            I don't necessarily agree with the other comments. The picture doesn't show enough to determine if this is a wet location or a damp location. See Article 100 locations, damp or wet. Article 330 allows MC indoors and outdoors, and only sets restrictions on wet locations and specifically allows only dry locations if embedded in masonry. So, this installation would be allowed in a damp location. It still needs to be properly secured.


            I know what I don't know, and I know where to go to find it!

              Are you referring to the white covers?

              If so, I am not so sure that is illegal. Definitely fugly though.

                Yep, white covers. It is a violation.

                  It may very well be. I am not scrutinizing the entire code book at this time, however, please don't just make a statement that it is a violation here. Cite the code section or sections that make it a violation.

                    Code reference or UL citation?

                      That MC would be considered fixed wiring and I highly doubt that cover is listed for that use.

                        I don't see the words fixed wiring in section 300.15, nor do I see anything that has any reference to that installation in that section.

                          "Where the wiring method is conduit, tubing, Type AC cable, Type MC cable, Type MI cable, nonmetallic-sheathed cable, or other cables, a box or conduit body shall be installed at each conductor splice point, outlet point, switch point, junction point, termination point, or pull point."
                          The boxes and fittings must be listed for the use, 330.40, and I doubt that a box cover is listed for connection to fixed wiring.
                          You may well be the sharpest tool in the box, but in the end you are still a tool.

                            Now we are getting somewhere. I don't agree with you. 330.40 requires the fitting to be listed not the boxes or covers. Read it again, or I am sure someone here will paste it that has that ability.

                              There is a box for the splice etc.

                              Where does that section say anything in regards to that cover.

                              Flexible raceways can be attached to box covers, common for powering office partitions/cubicles.
