Do you know how to size the bonding jumper to use between the tank ground, pole ground, and neutral? Pole mount transformer is single phase. 13.8kV to 120/240. Mostly curious about neutral to pole ground bonding as this is required at transformer secondary. Secondary conductors are just a #12 hot and neutral for 120v. NEC 250.102 makes me think you would use a #8 minimum for bonding but that seems kind of large since my hot and neutral are smaller at #12.
