Editorial comment:

In doing service changes, I find moving the point of attachment from insulators on the structure to the mast a common task. If you have a mast, that's where the wires ought to be attached. Period.

In Nevada, the PoCo supplied the bracket. Here in Arkansas, I get one at the supply house. Either way, the cost is built into the job.

Is it required? Well, that's what the artwork in the PoCo standards shows ... looks like a requirement to me!
