5.2 Power Supply Requirements
The system must receive its power supply via a dedicated feeder run from the nearest Main
Distribution Panel (MDP).
The system is designed to operate on a three-phase plus neutral, five-wire Wye power source
(preferably a solidly grounded Wye source). The neutral wire is used in the NM sub-system only
and does not need to be routed to the CT PDU (i.e. five-wire connection).
NOTE
According to local regulations, a primary power disconnect device must be provided on the power line supplying the
CT PDU, see Power Input Distribution Box (PIDB) with MDP (A1),p.5-14.
