Wireway conduit penetrations
Posted: Wed Oct 14, 2009 5:18 pm
The town electrical inspector rejected a high voltage pre-fab electrical equipment enclosure which has a wireway around the top interior of the enclosure picking up lights, smoke heads and receptacles, because the conduits from the ceiling mounted components entered the wireway through cutouts in the top part of the bolt-on wireway cover (it is against the ceiling and has the cover facing horizontally). The cover could be removed with the conduits being attached to an extension of the wireway enclosure.
We complained that the conduits were held in place firmly but the inspector said that the conduits could only enter the wireway through the provided knockouts at the bottom of the wireway and not through the cutouts at the top of the horizontal cover. This would mean we would have to take the conduits down in front of the wireway covers and bring them up into the bottom of the wireway.
I can find nothing in the NEC code that addresses the entrance of conduits into wireways. Am I missing something? Thanks
