Note: Any voltage above 600 volts is referred to as high voltage in this UFC. Refer to
the Glossary for definitions.
13-6.2.1 High Voltage Terminations. All high voltage portable power cables will be
terminated at the ship end of the cable with an IEEE-48 class 1, heat shrinkable
termination specifically designed for SHD-GC cables. The termination device at the
service end of the cable must be compatible with the design of the dockside power
connection station (turtleback) and may be terminated the same as the ship end of the
cable or with a coupler plug that is compatible with the receptacle at the dockside power
connection station. The termination devices shall be assembled on to the cable per the
manufacturer's instructions. Terminate the SHD-GC cable ground and check
conductors within the cable breakout boot or to the appropriate termination pin integral
with the coupler plug. (See UFGS 26 05 33, Dockside Power Connections Stations, for
additional information.)
13-6.2.2 Example of Pier High-Voltage (4,160 Volt) Electrical Outlet Assemblies.
This assembly utilizes a three pole, 500-ampere, 4,160 volt receptacle with a matching
plug. Units have the Mine Health Safety Administration approval, are provided with a
safety interlock, and have been modified to remove a ground cable connector. Refer to
Figure 13-18.

13-6.2.3 High-Voltage, (4,160 Volt and 15 kV) Receptacle Protective Circuit
Breakers. These high-voltage, 4,160 volt, air or vacuum type, circuit breakers have a
long time trip set at 400 amperes and are key-interlocked with their associated
receptacles to prevent insertion/removal of the receptacle connector unless the circuit
breaker is open.
