We have, an existing conduit run starts from a pull box mounted on a wall in a large cooler (38.5F) is exposed to this temperature for about 50 feet, then goes thru an suspended ceiling that is insulated (not very well), (47.5F) on the other side of the suspended ceiling, we go back into the cooler and down towards a (1600A/480V) switchgear room.
The temperature at the ceiling of the S.G. room is 71.8F, the ceiling of the S.G. room is insulated & has "Great Stuff" foamed around the conduit, we have been experiencing condensation dripping from the set screw couplings of the EMT that feeds the S.G. room.
A creative idea was we insulate the EMT with a fiberglass insulation from the S.G. room up to the suspended ceiling and from the other side of the suspended ceiling (after that space is repaired) to the pull box following up with Duct seal at the pull box to keep the air out.
The S.G. room was installed to stop the condensation in the 1st place.
