Connecting power from the power plant to the PDU

Note 1: It is good installation practice to fully wire out a pedestal, even if only one or two columns are being installed at first. This facilitates future expansion to a four-module column. The number of wires depends on whether the requirements are for two feeds per column (standard), four feeds per column (enhanced reliability), or one feed per Common Equipment (CE) module.

Note 2: If only two modules are used in the column, set the CB2 and CB3 circuit breakers to OFF.
