Although the current supply was to be taken from an outsidesource, yet, inasmuch as there was a probability of a plant being in-stalled in the building itself at some future time, the three-wire systemof feeders and mains was designed, with a neutral conductor equalto the combined capacity of the two outside conductors, so that120-volt two-wire generators could be utilized without any change inthe feeders. Basement. The plan of the basement, Fig. 42, shows the branchcircuit wiring for the outlets in the basement, and the location of themain switchboard.
