Any work performed or carried out on an electrical installation, and includes the installing, constructing, erecting or repairing thereof, the altering of the structure, the replacing of any of its parts, the adding of any part thereto or the carrying out of any work thereon for the purposes of its maintenance.
An electrical instrumentation technician commissions, tests, diagnoses, and repairs building control systems like refrigeration, heating, and air conditioning. They also carry out installation and calibration of measuring instruments, transmitting and controlling devices and sensors. The measurement of these devices enables products to be manufactured according to exact specification, taking into account the safety of the personnel and the environment.
The most “common” type of electricians, these electricians work to install and maintain anything from lights to a complete wiring system of our home. Depending on experience, a residential electrician may instruct a team of workers and plan and draw electrical projects. Some of their basic responsibilities include:
Commercial installation electricians work in much larger projects than our homes, like offices and malls. The power systems in these establishments require a lot of electrical power as compared to residences.
Electrotechnical panel builders, as the name suggests, construct and manage electronic panels, such as those found in HVAC systems. These electricians use information technology and programmable logic controls to the wire and assemble large electrical control boxes for industrial machinery. They also have the ability to read electrical schematics and panel layout blueprints.
These specialist electricians are required to maintain and make repairs to machinery like fans, pumps, compressors, and transformers. They also dismantle and put back together electrotechnology components, wind and connect coils and rewind single-phase and three-phase induction machines for low power.
An industrial electrician works in giant power plants, chemical plants, manufacturing facilities and other types of large-scale building. These facilities require a lot of heavy machinery and equipment and more electrical work and power than residential or regular commercial buildings. Industrial electricians frequently have to move from one job site to another and need to get certified as an experienced industrial electrician, either during their apprenticeship or journeyman status.
Although these electricians have much of the same tasks as residential and commercial electricians, they do it while working on systems with low voltage, usually not more than 49 volts. This includes installing, diagnosing issues, repairing and maintaining internet systems, land-line telephone systems, closed circuit television systems, home entertainment system, fiber optics network, LAN and WAN networks, cable television and fire and security alarms. Some electricians also specialize in electronics for ships, planes, trucks, and trains.
Electrical contractors are small business owners who have a crew of electricians that can perform jobs in residential, commercial and industrial settings. States regulate licensing of contractors and usually require them together become a master electrician or hire one to supervise them. They also require a certain level of insurance
This is the highest qualification for an electrician. They do not just work on commercial and industrial jobs; they can also manage a team of journeymen and apprentices. They also plan projects and assign tasks to other workers.
To become a master electrician, one needs to work certain hours under the supervision of a master electrician and must be working in the field for several years. After he has acquired expert knowledge, the electrician can take the state-approved Master Electrician Certification program and a state-specific exam to be certified as a master electrician.
