I have a dust collector installed outdoors on the roof of a building. The conduit runs out of the wall of the building and about 40 feet across the roof to the dust collector via 3/4" IMC. Where does the sealoff need to be installed? Where would the transition to unclassified area occur? I'm thinking maybe the seal would be required at the wall. Could it be installed closer to the dust collector? Maybe 15ft away? Thanks.
Sealoff Location?

Read either 501.15, 502.15 or 503.15 depending on the classification of your area and the criteria should be outlined there. Class II?
