Street Light Maintainer a)
Shall have completed a certified level II training from a recognized Power Lineman training program which includes: 1. 2. 3. 4. 5. 6.
Limits of approach Street light circuits Aerial devices Electrical theory Electrical awareness Personal protective equipment
b) Hands-on training which includes: 1. Energized secondary work 2. Connecting relays 3. Connecting ballasts etc. Note: Streetlight maintainers may work only on secondary voltage equipment, i.e. relays, ballasts, photoelectric controllers, secondary connections etc. As well, they shall install street light arms no closer than 3.0 m to primary conductors. Work within the 3.0 m safe limits of approach shall require written authorization from the Electrical Supply Authority. They are allowed to apply rubber blankets or line hose to conductors or apparatus energized below 750 volts. For work inside safe limit of approach >750V, the contractor shall be “Approved” by the Electrical Supply Authority.
4.0
Equipment The Contractor shall provide a truck equipped with an insulated aerial lift device and bucket that is adequate to reach all streetlights on the system. The Contractor shall also provide all the necessary vehicles for the transportation of personnel and equipment. A flashing lane changer (arrow board) shall be mounted on the rear of the vehicle at a height of 1.75 m from the bottom of the sign to the road. The sign shall meet Ministry of Transportation of Ontario specifications pertaining to such signage. The vehicle shall also be equipped with a system of four way flashing lights and a rotating light on the roof at the rear left corner.
5.0
Procedures For Trouble Shooting The following are some considerations for trouble shooting street light outages. For details steps, refer to the flow charts in Appendix I. 5.1
What is the nature of the complaint? Multiple lights out or just one, cycling on and off, Etc. Knowing this type of information will be a tremendous help in zeroing in on the problem.

5.2
What is the most likely thing to fail? The lamp. Unless there is good information to indicate that there is no lamp problem, first replace the lamp and blind the PEC to test the new lamp. The rationale for always changing the lamp is that it may be at its end of life cycling mode. Note:
6.0
When changing a lamp at night, remove the PEC to de-energize the luminaire. This turns off the high voltage pulses for personal safety and protection of the lamp and socket.
5.3
Although photoelectric controllers (PEC) normally fail in the ON state, there is a possibility that their contacts have burned open. Change the PEC.
5.4
Perform a quick visual inspection inside the luminaire to check for burned wiring, overheated ballast, flashed lamp socket, loose wiring connections, etc. Depending on the problem, it may be necessary to change the luminaire.
5.5
Check voltage (at terminal block, then hand hole or overhead secondary) to ensure that fuses and wiring are good.
5.6
In the unlikely event that the new lamp was defective, replace lamp again with another new one and double-check wiring connections.
5.7
Replace luminaire as a last resort.
