Conduit And Loom - Detroit Diesel DDEC VI Application And Installation

CONDUIT AND LOOM

Conduit must be used to protect the harness cable and cable splices.
The conduit must not cover any connectors, switches, relays,
fuses, or sensors.
The following guidelines should be used when designing a harness:
Wires should be sized and cut to near equal length prior to
installing conduit.
□ The distance between the back of the connector or other listed devices to the end of the
conduit should not exceed:
1.0 in. (25 mm) for a single connector/device
□
3 in. (75 mm) for multiple connectors/devices
□
□ All cable breakouts and conduit ends must be secured in place with conduit outlet rings or
tape.
Criteria: Conduit and Loom
Due to the wide variety of operating conditions and environments, it is the responsibility
of the OEM to select a conduit that will survive the conditions of the specific
applications. Flame retardant convoluted polypropylene conduit or equivalent may be
used for most installations. Heat retardant nylon conduit or oil, water, acid, fire, and
abrasion resistant non-metallic loom conforming to SAE J562A
diameter of conduit should be selected based on the number of wires being protected.
* If non-metallic loom is used, secure the ends with tightly wrapped nylon straps to prevent
unraveling.
Conduit should cover the wires without binding and without being excessively large.
