This Bursts My Bubble
The cover on this receptacle box has a few problems. First, it is not meant to be installed vertically with the cover flipping open to the side. It is designed to be installed horizontally with the cover flipping up. When used correctly, this enclosure would be weatherproof when the cover is closed. Not following instructions included with a listed product is a violation of Sec. 110.3(B). Secondly, it is not weatherproof while the attachment plug is inserted. Section 406.9(B)(1) requires this outdoor wet location receptacle enclosure to be weatherproof while in use. A “bubble cover” would have been a better option here. Section 406.9(B)(1) also requires any outlet box hood used for this purpose to be listed and identified as “extra duty.” That same Section also requires 15A or 20A, 125V and 250V receptacles installed in wet locations to be listed and identified as weather-resistant type receptacles. The liquidtight flexible metal conduit (LFMC) connected to the box is not properly secured within 12 in. of the box as required by Sec. 350.30(A). Section 350.10(3) permits LFMC to be used for direct burial applications where the LFMC is listed and marked for direct burial.
Messy MC Cable Installation
Whoever installed these MC cables was apparently looking to take the easy way out. They used cable ties to secure the MC cables to an existing PVC conduit instead of installing a new raceway or independently supporting the MC cables. Using a raceway to support cables is a violation of Sec. 300.11(C), unless the raceway is identified as a means of support. Section 352.12(B) also prohibits the PVC conduit from supporting any equipment other than conduit bodies as described in Sec. 352.10(H). The installer also yanked the cover off the PVC conduit body to splice the conductors in the raceway with the conductors of the MC cables. Section 300.15 requires a box or conduit body to be used when splicing or terminating conductors in MC cables. The lack of a box or enclosure for these splices creates a violation of Sec. 300.12, since there is no electrical continuity between the metal cable jackets of the MC cables. The lack of a cover for the conduit body is a violation of Sec. 314.25. Lastly, the lack of any fittings on the ends of the MC cable could leave sharp edges able to damage the insulation of the contained conductors and could be considered a violation of Sec. 300.4.
