	It depends on how the installation is intended to be run, about which no information is available here. How about the HV Electrical Engineer that designed it? Even if the individual is unavailable, the design brief document should exist somewhere. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	You have a brand new power plant and you don't have any engineering documents or access to an engineer or electrician. I don't believe you. __________________ "Don't disturb my circles." translation of Archimedes last words

	Homework! At least let's hope it's homework. Pity the poor people depending on power from this new plant with no competent operators.
