I'm bringing feeder duct into an 800A fused disconnect via a flanged end. Conductors will link these lugs to the disco switch lugs, possibly passing through a CT cabinet on the way. They will not be in conduit (other than a possible pair of 4" nipples if the CT cabinet is used.)
Are these considered to be in a raceway, or free air, or something else entirely?
310.16 asks for a lot more copper than 310.17 does, and I don't think there is any 75?C limitation on bare lugs.
thanks...
