When installed in a separate DC conduit, 18 AWG wires are required for installation.
Although it is recommended that DC pulser wires be run in a conduit separate from AC wires,
they can be combined in the same conduit with AC wires providing UL-Listed cable with the
following specifications is used:
• Conductor: 18 AWG stranded wire. Number of conductors to be determined by pulser
• Shield: Foil-wrapped 100% coverage and/or tinned copper braid 90% coverage
• Drain Wire: Stranded, tinned copper, 20 AWG or larger/or braided shield
• Voltage Rating: Maximum operating voltage of 600V
• Environmental: Gas- and oil-resistant; suitable for wet or dry locations.
Gasboy can supply Belden 1063A (P/N C09655) which is a UL-Listed, 4-conductor cable that
meets the requirements listed above.
Note: Belden 1063A is UL-Listed but not CSA listed.
