National Electrical Installation Standards

Standards as High as Your Own

Wednesday, September 18, 2019


NEC Article 350.30 (A) Exception No. 4, states following: “Lengths not exceeding 1.8 m (6 ft) from the last point where the raceway is securely fastened for connections within an accessible ceiling to luminaire(s) or other equipment. For the purposes of 350.30, listed LFMC fittings shall be permitted as a means of securement and support.” 1. I am looking for last sentence clarification “For the purposes of 350.30, listed LFMC fittings shall be permitted as a means of securement and support.” Is this only applicable to Exception 4 for the ceiling luminaries or is it applicable for entire 350.30 (A) and (B) article? 2. Exception 4 allows LFMC fittings as means of securement and support. Do the fittings have to be specifically listed for LFMC support or can they just be listed for use with LFMC?

Thanks Chris


Hey Chris thanks for your question. Standard listed fittings are acceptable for securing and supporting. You are not the only one that noticed the inconsistency and an additional sentence is being added to the 2020 NEC, 350.30 (A) to allow listed fittings to be used for securement and supporting for all of the exceptions to that section.
