In a Class II, Division 1 location, which type of conduit sealing is required for a conduit that passes from the hazardous area to an unclassified area, where the conduit contains wiring for a dust-ignitionproof motor?
No seal is required if the conduit is less than 2 inches in trade size.
A seal fitting is required within 10 feet of the boundary, but not necessarily at the boundary, if the conduit enters a dust-ignitionproof enclosure.
A seal fitting is required at the boundary of the hazardous and unclassified locations, and all connections in the sealing fitting shall be accessible.
A seal fitting is required within 18 inches of the boundary, and shall be installed in the conduit or tubing to prevent the passage of dust or fibers.
