Specifications

90 of 104
- Type SO or Type SEO cord with a WA suffix, rated at 600 volts at not less than 194 degrees
Fahrenheit (90 degrees Celsius)
Electrical cord or conduit shall not be attached to chassis suspension components, water or fuel lines,
air or air brake lines, fire pump piping, hydraulic lines, exhaust system components, or low voltage
wiring. In addition the wiring shall be run as follows.
- Separated by a minimum of 12 inches (305 mm), or properly shielded, from exhaust piping
- Separated from fuel lines by a minimum of six (6) inches (152 mm) distance.
Electrical cord or conduit shall be supported within six (6) inches (152 mm) of any junction box and at
a minimum of every 24 inches (610 mm) of continuous run. Supports shall be made of nonmetallic
materials or corrosion protected metal. All supports shall be of a design that does not cut or abrade
the conduit or cable and shall be mechanically fastened to the vehicle.
Wiring Identification
All line voltage conductors located in the main panel board shall be individually and permanently
identified. The identification shall reference the wiring schematic or indicate the final termination
point. When prewiring for future power sources or devices, the unterminated ends shall be labeled
showing function and wire size.
Wet Locations
All wet location receptacle outlets and inlet devices, including those on hardwired remote power
distribution boxes, shall be of the grounding type provided with a wet location cover and installed in
accordance with Section 210-7 "Receptacles and Cord Connections" of the NEC.
All receptacles located in a wet location shall be not less than 24 inches (610 mm) from the
ground. Receptacles on off-road vehicles shall be a minimum of 30 inches (762 mm) from the ground.
The face of any wet location receptacle shall be installed in a plane from vertical to not more than 45
degrees off vertical. No receptacle shall be installed in a face up position.
Dry Locations
All receptacles located in a dry location shall be of the grounding type. Receptacles shall be not less
than 30 inches (762 mm) above the interior floor height.
All receptacles shall be marked with the type of line voltage (120-volts or 240-volts) and the current
rating in amps. If the receptacles are direct current, or other than single phase, they shall be so
marked.
Listing
All receptacles and electrical inlet devices shall be listed to UL 498, Standard for Safety Attachment
Plugs and Receptacles, or other appropriate performance standards. Receptacles used for direct
current voltages shall be rated for the appropriate service.
Electrical System Testing
The wiring and associated equipment shall be tested by the apparatus manufacturer or the installer of
the line voltage system.
The wiring and permanently connected devices and equipment shall be subjected to a dielectric voltage
withstand test of 900-volts for one (1) minute. The test shall be conducted between live parts and the
neutral conductor, and between live parts and the vehicle frame with any switches in the circuit(s)
closed. This test shall be conducted after all body work has been completed.
