Production Specification
SVI #847 Page 92 of 107 September 18, 2012
Bonding
The neutral conductor of the power source shall be bonded to the vehicle frame. The neutral bonding connection shall
occur only at the power source. In addition to the bonding required for the low voltage return current, each body and each
driving or crew compartment enclosure shall be bonded to the vehicle frame by a copper conductor.
The conductor shall have a minimum amperage rating, as defined in 310.15, “Ampacities for Conductors Rated 0–2000
Volts,” of NFPA 70, of 115 percent of the rated amperage on the power source specification label.
A single conductor that is sized to meet the low voltage and line voltage requirements shall be permitted to be used.
Ground Fault Circuit Interrupters
In special service vehicles incorporating a lavatory, sink, toilet, shower, or tub, 120 V, 15 or 20 A receptacles within 6 ft
(1.8 m) of these fixtures shall have ground fault circuit interrupter (GFCI) protection. GFCIs integrated into outlets or circuit
breakers or as stand-alone devices shall be permitted to be used in situations.
Power Source General Requirements
All power source system mechanical and electrical components shall be sized to support the continuous duty nameplate
rating of the power source.
The power source shall be shielded from contamination that would prevent the power source from operating within its
design specifications.
Power Source Rating
For power sources of 8 kW or larger, the power source manufacturer shall declare the continuous duty rating that the
power source can provide when installed on fire apparatus according to the manufacturer’s instructions and run at 120°F
(49°C) air intake temperature at 2000 ft (600 m) above sea level.
The rating on the power source specification label shall not exceed the declared rating from the power source
manufacturer.
Access shall be provided to permit both routine maintenance and removal of the power source for major servicing. The
power source shall be located such that neither it nor its mounting brackets interfere with the routine maintenance of the
fire apparatus.
