Installs and repairs electrical cable and wiring systems for ship's power, light, communications, and control circuits, following blueprints and wiring diagrams.

Work involves most of the following:

Installs conduit to bulkheads with brackets and screws, using hand tools. Threads wires through conduits to terminals, such as connection boxes, circuit breakers, voltage regulators and switch panels. Connects power-supply circuits to radio, radar, fire control and other electronic equipment. Tests electrical characteristics, such as voltage, resistance and phase angles in circuits, using volt meters, ohmeters, and phase rotation indicators, constructs and repairs switchboards for main propulsion, other power and various communication systems of ship, using hand tools and power drills.
