![]() ![]() In the 2023 NEC ®, Section 300.4(G) was revised to make it clear that insulated conductor’s size 4 AWG and larger require protection from abrasion where entering a cabinet, enclosure, box, or raceway BEFORE the conductors are pulled or installed. To comply with the red tag, the electrician knew he had to take all the conductors loose from their termination and slide a bushing over them to thread on to the raceway, and then re-terminate all the conductors before the work could be re-inspected. Before hinged electrical fittings became available (see image), the electrician’s heart would sink when the electrical inspector requested a bushing on a conduit containing large conductors that were difficult to wrestle into place and terminate. One of the most common inspector red tag items after wires are pulled is to request an insulated bushing on the end of a raceway or fitting where 4 AWG or larger insulated conductors enter an enclosure. Code Change Summary: Protection for insulated conductors 4 AWG or larger must now be installed before installing the conductors.
