Replacing existing underground conduits & wire to outdoor above ground tanks & fuel dispensers - one Unleaded and one is Diesel. They are side by side. The dispensers and tanks have 240 VAC Pumps and 120 VAC Controls.
We will be using multi-conductor M/C-HL with a gas / vaportight continuous sheath. Since the Diesel Dispenser is within 20 feet of the Unleaded Dispenser and its electrical enclosures both systems are Class 1 Div. 2 from what I understand.
Do we need to use the Haz. Loc. Explosion Proof Sealing M/C-HL Connectors for this installation ?
