Conduits must have EYS seal fittings sump/dispenser pan and cover WarningA installed in accordance with NFPA L,WoIL f 70 (National Electric Code) and NFPA 30A(Automotive and Marine Service Station Code). Failure to seal conduits in accordance with NFPA 30A, and NFPA 70 could allow flammable vapors to travel through the conduit in the t2 or 3/ato°h ATG console.An explosion could dgidult result causing serious injury, property tontlutc ATG loss, or death. console You must install a weatherproof, electrical junction box inside each manhole.The junction box should be installed high on the manhole wall to prevent it from being submerged during heavy rains.
