Hello, I am new here and I'm an electrician in California. On this job, we are mounting transformers (480V delta to 208V wye) out on a floating dock system. There is an appropriately sized equipment ground conductor coming in with the 480V conductors feeding the line side. The floating dock system is all constructed of 2" X 2" X 1/8" wall aluminum square tubing with plastic floats bolted to the bottom and deck boards screwed to the top. My question is, what is the best way to install the grounding electrode conductor? My idea was to attach it directly to "building steel" as I would in a building, then have a monster ground conductor bonding the whole dock system to the ground rod on shore (where the 480V comes from). The city is suggesting we run another ground wire parrallel to the equipment grounding conductor, or just upsize the equipment grounding conductor and use it for both the equipment ground and the grounding electrode conductor. What do you think? Thanks brothers and sisters, Ben
