I currently only have the NEC 2020 edition available, but based on my review of section 358.6 regarding EMT listing requirements, it states that EMT, factory elbows, and related fittings must be listed.
I believe it’s reasonable to conclude that similar criteria will apply in NEC 2023. The emphasis on mounting hardware being listed highlights the ongoing commitment to safety and compliance in electrical installations. As we move forward, it’s essential for professionals in the field to stay updated on these changes to ensure that all components meet the necessary standards for reliability and performance. Would NEC 2023 require conduit mounting hardware to be listed? It seems likely, as the industry leans towards strict adherence to safety protocols.
Okay, so NEC 2023 now says that all conduit mounting stuff needs to be listed. This matches what they already ask for with EMT, fittings, and factory elbows since NEC 2020. Just make sure you keep up with these changes to stay safe.
