9.4 Conduit Seal Fittings for Cables
IMPORTANT: To comply with Article 501 of the National Elecrical Code, Seal-offs must be
installed where I.S. wiring enters conduit. Install one conduit seal fitting in the manhole where
the conduit leaves the junction box and one in the building before the conduit goes into the
console.
WARNING: The Tank-Probe cables must be sealed before they go into the
I.S. barrier (explosive fumes can travel through the cable jacket). This will
keep explosive fumes away from the I.S. barrier.
1. Prepare the Cable: Remove a sufficient length of the cable jacket so that the conductor wires can
extend into the conduit seal fitting (approximately 3 inches [7.62 cm]).
IMPORTANT: Make sure you do not cause damage to the conductor wire insulation!
2. Pull the prepared Cable through the assembled conduit and fitting so that the conductor wires extend
into the conduit seal fitting.
3. See the manufacturer's instructions that came with your Conduit Seal Fittings for the correct procedure
to fill the seal cavity with an applicable sealing compound.
IMPORTANT: Make sure that the open ends of the prepared cable inside the fitting are
completely sealed. This will prevent the flow of explosive fumes through the Cable jacket.
