voltage withstand test of 900 volts for one (1) minute. The testing shall be performed after all body work has been
completed.
The test shall be conducted as follows:
1) Isolate the power source from the panel board and disconnect any solid state low voltage components
2) Connect one lead of the dielectric tester to all the hot and neutral buses tied together
3) Connect the other lead to the fire apparatus frame or body
4) Close any switches and circuit breakers in the circuit(s)
5) Apply the dielectric voltage for one (1) minute in accordance with the testing equipment manufacturer’s
instructions
The electrical polarity of all permanently wired equipment, cord reels and receptacles shall be tested to verify that
wiring connections have been properly made.
Electrical continuity shall be verified from the chassis or body to all line voltage electrical enclosures, light
housings, motor housings, light poles, switch boxes and receptacle ground connections that are accessible to fire
fighters in normal operations.
If the apparatus is equipped with a transfer switch, it shall be tested to verify operation and that all non grounded
conductors are switched.
Electrical light towers, floodlights, motors, fixed appliances and portable generators shall be operated at their full
rating or capacity for 30 minutes to ensure proper operation.
