National Electrical Installation Standards

Standards as High as Your Own

Wednesday, July 13, 2022


Greetings CQD,

Someone has refed an underground feed to a light pole coming up next to it with an LB unilet and a short GRC nipple. The only thing that I see wrong is that they drilled The side of the LB to gain access into it instead of using one of the threaded hubs. I said this is a code violation because they are not using the fitting for what it was listed and intended for? Am I correct if so what code would be reference for the violation?

Mike LaRosa



Hi Mike,

Thanks for the question. Section 344.6 requires rigid metal conduit and associated fittings to be listed. Listed products typically come with installation instructions. Based on the information provided, there is a clear violation of Section 110.3(B) which indicates listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.
