1.
Proper repair of 220/110 Volt wiring consists of replacement of the damaged wiring. When electrical casualty requires
expedient repairs, repair may be made by splicing. Splicing is authorized for repair of damaged cables if the remainder of
the cable is in good mechanical and electrical condition. The cable must be replaced in its entirety at the most opportune
time. For proper splicing methods, refer to FM 55-509-1.

To replace 220/110 Volt wiring:
WARNING
Replace or repair components only after the affected circuit has been secured, locked
out, and tagged out. Performing replacement with the circuit energized may result in
damaged equipment and serious injury or death to personnel.
a.
Remove any inteference or covers that restrict access to the end of the wiring assembly.
b.
Set the multimeter to the Vac (Volts alternating current) setting and check the voltage at the wiring's terminals (1). If
no voltage is noted, proceed to the next step. If voltage is noted, check that the shore power and diesel generator
are properly secured.
c.
Label the wiring near the wiring's terminal (1) or make a sketch of the work area to permit proper reassembly.
