...and yet, the OP is playing with an 11KV switching system...why would someone who is asking such a fairly "basic" question be allowed to come within 100 feet of such a device? That's a situation with "accidental electrocution" nearly written all over it. I just don't understand how someone gets into such a situation, with limited knowledge, but then decides "yeah, I can do this" - as if the system will be forgiving if they make a mistake. It certainly has the ring of the "Dunning-Kruger effect"...
