Am helping a client with a light pole design for Canada. They only supply the pole, so no luminaire, hood, or wiring. There’s been some conflicting discussion about grounding terminals required to be supplied on the pole to ground the luminaire when installed onsite. The pole currently has a primary grounding terminal at the base. In practice, does the pole itself need an additional terminal at the top for the luminaire to be bonded to, or is the grounding wire connected from the luminaire down to the primary terminal considered sufficient?
Well, now lets go to the ‘spec’, tediously written, and most times drawn within the plans. Some spec a 8’ rod, cadwelded to #6 or 4 cu, up into the pole base. Some spec a 10’ rod, or some spec 20’ min., #x rebar, with #4 Cu.
Thinking back, one that jumps to mind is site lighting for a new bank. Spec was 10’ rod, cadweld, #4 Cu. No sweat, yje EC did his thing & insp was OK. Poles arrive, I just was driving by, ‘sparky’ had the pole on his shoulder, all 15’ of it. Turns out the poles is the fixture schedule were FIBERGLASS!!! Duh,
