3.1 Conduit/Wiring Requirements
IMPORTANT:
All wiring and conduit runs must conform to the National Electric Code (NFPA
No. 70), Code for Motor Fuel Dispensing Facilities and Repair Garages (NFPA No. 30A) and
all national, state and local codes.
All wiring running to the system must be installed in threaded, rigid metal conduit and have the
required sealoffs. AC and DC power wires can share conduit, provided they meet the Petro-
Net™ wiring specified; otherwise AC and DC power wires must be installed in separate
conduits.
3.1.1 Conduit Sealing
Conduit entering the hazardous area must have a seal-off installed 18 inches (46 cm) above grade to prevent
liquid or fumes from entering the area.
When running shielded cable through a seal-off, strip the cable jacket back so about three (3) inches (7.6 cm)
of jacketed cable protrudes past each seal-off.
WARNING: Shielded cable is NOT vapor-tight! DO NOT damage the shield
wire! Stripped section must be in the sealed-off area.
