All circuits shall otherwise be wired in conformance with SAE J1292,
Automobile, Truck, Truck-Tractor, Trailer, and Motor Coach Wiring.
Wiring and Wire Harness Construction
All insulated wire and cable shall conform to SAE J1127, Low Voltage Battery Cable, or SAE J1128, Low Voltage Primary
Cable, type SXL, GXL, or TXL.
All conductors shall be constructed in accordance with SAE J1127 or SAE J1128, except where good engineering
practice dictates special strand construction. Conductor materials and stranding, other than copper, shall be permitted if
all applicable requirements for physical, electrical, and environmental conditions are met as dictated by the end
application. Physical and dimensional values of conductor insulation shall be in conformance with the requirements of
SAE J1127 or SAE J1128, except where good engineering practice dictates special conductor insulation. The overall
covering of conductors shall be moisture-resistant loom or braid that has a minimum continuous rating of 194°F (90°C)
except where good engineering practice dictates special consideration for loom installations exposed to higher
temperatures. The overall covering of jacketed cables shall be moisture resistant and have a minimum continuous
temperature rating of 194°F (90°C), except where good engineering practice dictates special consideration for cable
installations exposed to higher temperatures.
All wiring connections and terminations shall use a method that provides a positive mechanical and electrical connection.
The wiring connections and terminations shall be installed in accordance with the device manufacturer’s instructions. All
ungrounded electrical terminals shall have protective covers or be in enclosures. Wire nut, insulation displacement, and
insulation piercing connections shall not be used.
Wiring shall be restrained to prevent damage caused by chafing or ice buildup and protected against heat, liquid
contaminants, or other environmental factors.
Wiring shall be uniquely identified at least every 2 ft (0.6 m) by color coding or permanent marking with a circuit function
code. The identification shall reference a wiring diagram.
Circuits shall be provided with properly rated low voltage overcurrent protective devices. Such devices shall be readily
accessible and protected against heat in excess of the overcurrent device’s design range, mechanical damage, and water
spray. Circuit protection shall be accomplished by utilizing fuses, circuit breakers, fusible links, or solid state equivalent
devices.
If a mechanical-type device is used, it shall conform to one of the following SAE standards:
1) SAE J156, Fusible Links
2) SAE J553, Circuit Breakers
3) SAE J554, Electric Fuses (Cartridge Type)
4) SAE J1888, High Current Time Lag Electric Fuses
5) SAE J2077, Miniature Blade Type Electrical Fuses
Switches, relays, terminals, and connectors shall have a direct current (dc) rating of 125 % of maximum current for which
the circuit is protected.
Power Supply
A 12 V or greater electrical alternator shall be provided. The alternator shall have a minimum output at idle to meet the
minimum continuous electrical load of the vehicle, at 200°F (93°C) ambient temperature within the engine compartment,
and shall be provided with full automatic regulation.
