WARNING
Shore activity personnel open, rack out, danger tag and lock shore power
receptacle circuit breakers, test for no voltage, and ground load side of
shore power receptacle circuit breakers in accordance with below listed
tag out procedures or local activity prepared procedures. Disconnect
equipment such as potential transformers, meters or indicating lights that
could be damaged by a megohmeter test or cause a false reading.
13-7.4.1 Ensure voltage tester/detector is in proper operating condition by testing the
voltage tester/detector on a known energized source before testing shore power
receptacle.
13-7.4.2 Inspect key interlock for proper operation. Remove access cover to each
shore power receptacle one at a time and use the voltage tester/detector on the end of
a live line tool (hot stick) to ensure the receptacle terminals are deenergized. If no
voltage is indicated, retest the voltage tester/detector to re-verify it is working properly.
Clean each cover and receptacle. Inspect each cover gasket and each receptacle
gasket for cuts, tears, cracks and deformation. Inspect each receptacle conducting
surface for pitting, corrosion and evidence of overheating.
13-7.4.3 Remove grounds, for testing purposes, at load side of shore power receptacle
circuit breakers one at a time. Use a 5000 volt megohmeter and perform an insulation
resistance test on each receptacle phase to phase and each receptacle phase to
receptacle case (ground). Values shall be greater than 5 megohms.
13-7.4.4 Install shore power receptacle access covers.
13-7.4.5 Test for no voltage and install grounds at load side of shore power receptacle
circuit breakers.
13-7.5
Inserting Cable Plugs Into Receptacles (480 Volts and 4,160 Volts).
WARNING
Connections are to be made from the shore power receptacle toward the
ship's electric bus. When distance from ship's electric bus to the shore
power receptacle requires splicing of two or more cables, splicing should
be completed prior to making any ship or shore power receptacle
connections.
13-7.5.1 Use an approved voltage tester and ensure it is in proper operating condition
by testing the meter on a known energized source before testing shore power
receptacle terminals.
