Planning on installing a 1-1/4" PVC raceway between two buildings, approximately 8' off the ground. Raceway is for general 240V branch circuit conductors. Span is only 3' or so between buildings. Checking through the code, the height requirements/restrictions seem to be limited to open conductors. I could not find anything specific on conductors enclosed in raceways. Have I missed anything relative to height (min/max) restrictions/limitations for raceways between buildings?
