General Information:

This

procedure lists general guidelines for the isolation of non-essential systems.

●

Varies depending on which system is isolated.

Personnel/Time Required:

Crimp-on end caps, electrical tape or other insulating material.

Procedural Steps:

1. Insulate/isolate non-essential wiring or cabling with crimp-on end caps, tape, or any

other insulating material.

Secure wires to some structure and tag them for rapid

identification.

without it. Disconnect the cable leading to that particular control box at AM-1780 and

consider using field expedient means for intercom.

damaged.
