Our three winners this month include: Jim Follett, senior estimator, D&L Electric Co. Ltd., Houston; David Evans, electrical inspector II, City of Boca Raton, Boca Raton, Fla.; and Tom Holmes, owner, TSH Electric, West Islip, N.Y. Here are just a few of the many violations noted in this installation.
Because there are no locknuts securing the conduit to the cabinet, this results in a violation of 300.10, which requires raceways to be mechanically secure to boxes, fittings, cabinets, and other enclosures. In addition, the RMC does not appear to be securely fastened in place and supported as required by 344.30. There’s also a good chance there’s no bushing present inside the box, as required by 344.46.
This arrangement also violates the general bonding and grounding requirements noted in 250.4 and the equipment grounding requirements of 250.120(A). We can also see that no paint has been removed from the entry point. As noted in 250.12, nonconductive coatings shall be removed from contact surfaces to ensure good electrical continuity. The lack of a bonding type locknut or bushing also violates the bonding requirements of 250.90 and 250.96. If this is a service panel, we can cite Secs. 250.90 and 250.92(B).
Other general sections of the Code worth noting include Secs. 110.3(B) and 110.12.
