Here in the 1950's we still bracket ground on distribution. We are only required to use a pole band and EPZ on transmission. Our engineers actually told us that the neutral bracket acted in the same way a pole band did. They didn't have an answer for me when I asked what happens when the neutral is above where you could possibly put your feet. Silence and a blank stare followed that question. We get that a lot from engineering. It is a good idea to ground digger trucks, as for grounding bucket trucks, that is a crappy idea why would you want ground the chassis of a truck with an insulated boom. If you need to do that and expose your ground crews to an additional hazards you have bigger problems with your work practices than can be discussed here. I knew one of the guys who was killed in the Transmission accident on Grids property. He was a good lineman who was killed by a shitty operator. Wear your rubber gloves, put on pole guards, keep you body clear of the pole, keep clear of the truck. Most importantly have a plan, and if you change it in the middle, make sure everyone knows what the change is. Work safe.
