cuts, tears, cracks, and deformation. Inspect each receptacle conducting surface for
pitting, corrosion, and evidence of overheating. Operate each receptacle interlock
switch manually; movement should be smooth with no binding or sticking.
13-7.3.3 Use a suitable megohmeter (refer to paragraph 13-7.2.3.4) and test the
insulation resistance between each receptacle terminal and between each terminal and
ground. Minimum insulation resistance is two megohms for 480 volt receptacles.
Reinstall indicator light and phase meter fuses. Close shore power receptacle access
covers. Remove "DANGER" tags and locks from shore power circuit breakers and
receptacle circuit breakers for testing purposes. Replace with "CAUTION" or "SPECIAL
INSTRUCTION" tags in accordance with tag out procedures (use of "CAUTION" tags is
optional). Indicate on "CAUTION" or "SPECIAL INSTRUCTION" tags that if shore
receptacle power interlock and/or power control power transformer fuses are removed
or blown, shore receptacle power cover safety interlock will be inoperative. Warn that
voltage will be present if interlock fails.
13-7.3.4 Test shore power receptacle cover interlock switches and indicator lights as
follows:
13-7.3.4.1 Close shore power receptacle circuit breakers.
13-7.3.4.2 Shore power receptacles should be energized.
13-7.3.4.3 Ensure indicating lights are illuminated.
13-7.3.4.4 Open shore power receptacle access cover; receptacle circuit breaker should
trip and indicating light should extinguish.
13-7.3.4.5 Use an approved voltage tester and ensure it is in proper operating condition
by checking the tester on a known energized source before testing shore power
receptacle terminals.
13-7.3.4.6 Test shore power receptacle with the tester to ensure it has been
deenergized.
13-7.3.4.7 Close shore power receptacle access cover.
13-7.3.4.8 Open shore power receptacle circuit breakers.
13-7.3.4.9 Remove "CAUTION" tags (if installed) and attach "DANGER" tags and locks
to shore power circuit breakers in accordance with tag out procedures.
