Figure 13-6. Newer Double-Deck Pier Switchgear
Ship-to-Shore Pier Electrical Outlet Assemblies. Ships service is from
pier electrical outlet assemblies that contain either multiples of single pole or three-pole,
500-ampere receptacles rated either for 450 volts ships service, 4.16 kV ships service,
or 15-kV ships service as appropriate to the pier's ship electrical service requirement.
Receptacles may be interlocked with their associated substation secondary circuit
breaker for safety reasons. Figures 13-7 and 13-8 show three-pole outlet assemblies for
480 volt and 4.16 kV services respectively.
