What else is surprising is
There has been a whole lot of experts in the industry (since the late 1950's) study this. The cluster bar is widely considered as the best method to give a lineman the best chance in an accidental energizing or an induction incident.
Then a utility from Ohio says they think something vastly different is the only way, and look at how many "LINEMEN" say, " AAAAh, Okay!" That's the way to do it.
I have seen information presented and the studies conducted for the use of a cluster bar. I have seen the math prove that it works. It makes sense to me.
The other way AEP claims to work does not. Until it is proven to me I'm not jumping on. It must be proven and not leave me with any doubts. Not just because someone said so.
The guys who say they believe it without hard facts to support itare just little sheep looking for the butcher shop.
