We do a lot of work for the power companies. You know what a three phase is correct. All three lines are not even carrying the same voltage or frequency and sometimes one is a ground. To generate an arc a hot usually has to come in contact with a ground or different frequency of electricity. So the rope to get a good surge of electricity would have to cross two of the phases.

Matt actually you are wrong, a 3 phase true 3 phase is carrying the same voltages on Duquesne they are labeled A,B,C phase & will run stand alone nuetral or that nuetral is part of the secondary, an arc can be created many ways & your scenario is one of many, you say you do alot of work for the power companies?
you are not on Duquesne Lights vendor list & only contractors under contract with DL are allowed to work in close proximity to energized conductors (inside the 10ft rule) also to work on the property you have to be a union contractor............Im a little confused as I keep reading your posts that state such, First Energy is the same way, not to be ignorant but you dont have the ability to insure yourself according to their procurement standards!
So whos your Inspector from the utility?
