13-7.2.3.3 Clean cable plugs. Inspect each plug conducting surface for pitting,
corrosion, and evidence of overheating. Inspect cable connectors for pitting, corrosion,
and evidence of overheating. Apply a light coat of approved grease to cable
connectors.
13-7.2.3.4 Use a megohmeter to measure the insulation resistance between cable
assembly conductors and each conductor and ground. A 500 volt megohmeter shall be
used for 450 volt cables and a 5,000 volt megohmeter shall be used for 4,160 volt
cables.
WARNING
Test the insulation resistance of each cable before each use.
13-7.2.3.5 Minimum insulation readings for 480 volt service cables shall be 2 megohms.
Minimum insulation readings for 4,160 volt and 15 kV service cables shall be 5
megohms.
13-7.2.3.6 Record insulation resistance values. Record lowest acceptable value on ship
connect/disconnect form. Replace the cable if it does not meet insulation resistance
requirements.
13-7.2.3.7 Use the megohmeter to verify phase identification markings of the cable
assembly to ensure proper orientation.
13-7.2.3.8 Tag shore power cable assembly with "DANGER-HIGH VOLTAGE" signs.
Barricade the work area surrounding the ship's shore power receptacles.
13-7.3
Checking 480 Volt Shore Receptacles.
WARNING
Shore activity personnel open, danger tag, and lock shore power
receptacle circuit breakers in accordance with below listed tag out
procedures or local activity prepared procedures. Disconnect equipment
such as meters or indicating lights that could be damaged by a
megohmeter test or cause a false reading.
13-7.3.1 Remove indicator light and phase meter fuses. Ensure voltage tester is in
proper operating condition by testing the voltage tester on a known energized source
before testing shore receptacle power terminals.
13-7.3.2 Open access cover to each shore power receptacle and use a voltage tester
to test terminals in each shore power receptacle to ensure that they are deenergized. If
no voltage is indicated, retest the voltage tester to re-verify it is working properly. Clean
each cover and receptacle. Inspect each cover gasket and each receptacle gasket for
