The electrical worker makes repairs that can be accomplished by removing, replacing, tightening, splicing, soldering, and insulating defective wiring, controls, equipment, and fixtures such as broken and bare wiring, burned out switches and relays, loose connections and fittings, damaged light fixtures, re-lamping fixtures and poorly operating thermostats. Electrical worker receives work orders, oral instructions, and wiring diagrams that indicate the nature of the repair or installation to be made, the layout and placement of circuitry, fixtures, and controls, and the types of wiring, parts, and equipment installed. They locate broken, worn, damaged, or poorly operating wiring, fixtures, controls, and equipment through visual check or through use of a small variety of test equipment, for example, test lamps, voltage testers, ammeters, and polarity testers. They complete needed repairs to installed systems, and rearrange and hook up items such as outlets, switches, light fixtures, regulators, and circuit breakers.
Skill and Knowledge
The electrical worker require knowledge of where fixtures, wiring, and controls, such as light switches, circuit breakers, fuses, relays, and outlets, are installed and how they operate. They must read and follow wiring diagrams that specify where wiring, fixtures, and controls are installed or are to be hooked up and show the type of wiring, fittings, and equipment installed or to be used. Electrical workers must have the skill needed to remove and replace fixtures and controls, and to make repairs such as tightening connections, using the correct wire nut device, and soldering loose wire leads to contact points. They must also have the skill needed to rearrange old or install new outlets, relays, switches, and light fixtures in existing systems, and to test circuits to see if they are complete after making repairs or installations. The electrical workers must have the skill needed to measure, cut, and bend wire and conduit to specified lengths and angles. They must have skill in the use of hand tools and portable power tools, such as screwdrivers, pliers, wire cutters, strippers, drills, soldering irons, and manual or power conduit benders and threads; and a limited variety of test equipment, for example, meggers, test lamps, and ammeters.
The electrical worker, will be advise of lay outs, and assigns work orally or through work orders and wiring diagrams. Electrical worker selects tools, decides on methods and techniques to use, and carry out the work with little check during its progress. They use materials called for in work orders and schematic drawings, or obtain replacement parts by comparison with samples such as switches and wall outlet fixtures. They replace worn or bad switches, relays, and outlets by unscrewing or cutting wiring from connections, inserting the replacement, and splicing, tightening, and soldering wiring to connections. They also install or rearrange light fixtures, switches, and outlets by following schematic drawings that provide the exact work specifications, for example, the location where the electrical wiring is to be hooked into the installed system, the type, size, and measurements of wire, conduit, couplings, and fittings to use, and the type and placement of the electrical device to be installed. Routine repair and maintenance duties are accomplished independently; if unusual problems arise, or if installation or repair of unfamiliar or complex industrial electrical systems is assigned, the VA COR checks to see that completed work meets requirements.
Electrical workers make repairs and installations from ladders, scaffolding, platforms, and other hard-to-reach places. This requires electrical workers to stand, stoop, bend, kneel, climb, and work in tiring and uncomfortable positions. Electrical workers frequently lift and carry tools, equipment, and parts that weigh up to 9 kilograms (20 pounds) and, less often, up to 18 kilograms (40 pounds). Occasionally, they lift or move with assistance moderately heavy objects weighing more than 18 kilograms.
