It seems customary for the power company to land their delta high-leg conductor on "C" phase on the line side of the service. Section 408.3(E) tells us to terminate the wire on "B" phase in our service panel. Isn't it customary for the power company to give us A-B-C phase rotation? When we switch the wires we are changing that rotation. Don't we want to be maintaining A-B-C rotation in our installations?
