Grounding of Canopy System

[arkiesparky]

I've got an unattended fueling station that has a small control building located away from the canopy.

The electrical circuits feeding the submerged pumps, lighting, etc. each have a ground wire pulled with the circuit.

The canopy columns do not have a bond made to the concrete pad rebar and I'm concerned about lightning.

Question: How do I go about bonding the canopy system to the main electrical service and involve lightning protection for the canopy itself?

I wonder if you would be doing a disservice by running a ground wire from the canopy back to the control panel GE. You might just be encouraging lighning to come that way.

That is one of my concerns as well.

The new codes require the vent stack to extend to 5' above the highest point of the canopy. I think this becomes a lightning rod at this point and I'm concerned the canopy could become energized in the event of a lightning strike.

I want to make sure the ground path is effective, but without causing harm to the electronics back in the control building.
