12VDC WIRING REQUIREMENTS:
• 2-gauge minimum copper stranded battery cable shall be used for 12Vdc main supply
lines. All cable runs shall be full length, no splices. All cable terminals shall be staked
and soldered. All cable shall be enclosed in convoluted polyethylene tubing and the ends
of the cable shall be sealed with color-coded shrink-wrap identifying the function of the
cable.
• All added electrical circuits shall be protected from over-current by resettable circuit
breakers appropriately rated for the load. Only circuit breakers shall be used in the
installation of added electrical wiring (plug type fuses are unacceptable).
• Circuit breaker functions shall be identified by engraved or printed labels.
• All added wiring for load runs shall be AWG 8, 10, 12, 14 and 18 and must conform to
MIL-W-16878F.
• Wire terminals for added circuits must conform to MIL-T-7928. Terminals shall be
insulated, insulation grip, TYPE II, CLASS 2 and shall be crimped with tooling
recommended by the terminal manufacturer.
• All wiring shall be numbered or lettered on 6" centers minimum.
• Wiring shall be protected from chafing and abrasion with convoluted polyethylene
tubing (wire loom) as required.
• Where wire passes through sheet metal, bulkheads and structural supports, plastic
grommets shall be used to protect both wiring and wire looms.
• All wire bundles shall be tied with trimmed nylon ties.
• Extreme care shall be exercised to provide for easy serviceability of the system in future
years.
• Extreme care must be taken in the installation to avoid the engine manifold, engine
exhaust, and muffler, which could expose the wiring to severe overheating during long
periods of operation. Proper insulation and heat deflection panels must be installed in
such areas.
• A high-current 12Vdc system wiring schematic shall be provided.
• These are the minimum acceptable 12Vdc wiring requirements.
