Electrical works involve the conversion of electrical energy into some other form of energy. Electrical work usually involves the movement of a large number of particles and the utilization of energy to do so. The energy can be in the form of heat or in the form of static electricity. There are many other forms of electrical energy and all these forms can be transformed into electrical energy for the purpose of performing electrical works. There are many different types of electrical works and all these forms can be categorized into three main categories: home works, industrial works, and mechanical works.

Home Works: All electrical works that are performed at home include installation of electrical appliances such as cookers, refrigerators, air conditioning units, home security systems, toaster ovens, dishwashers and washing machines. Installation of electrical works is usually done by licensed electricians. Other home works include installation of lighting fixtures. Installation of outlets is also part of home works. Installation of wiring is required for wiring electrical appliances to work.

Industrial Works: All electrical works that are required for the purpose of carrying out industrial functions are usually performed by professionals. Electricians who carry out industrial works must have professional skills and this is required if they are to carry out job related tasks such as installation of electrical appliances, wiring, and installation of outlets. Other jobs that require electrical skills are maintenance of industrial machinery, installation of cable ducts etc. All these tasks are normally performed by trained professionals.

Mechanical Work: All electrical works that are required to carry out mechanical function must be performed by professionals. Some of the electrical work which is a mechanical process is notifiable. A mechanic cannot work on any part of an appliance that is notifiable. Some of the parts of a mechanical work that are notifiable are: heating elements, cooling fans, pumps, and combustion engines.

Home-related Projects: Electrical installations that are required for day-to-day home usage can also be notifiable. If an electrician is required to carry out a job related to wiring or installs outlets in the home, he must have a good quality electrical works. For instance, installing an extension cord to a wall socket is notifiable. Installing lighting fixtures in the house is also notifiable if the lighting fixtures are in good quality and are fit properly. Any electrical installation that is noticated by a professional should be carried out by a good quality electrical contractor.

All electrical works should be done by qualified and licensed electricians and all electrical installations should be done by well qualified and licensed electricians. In addition, all electrical installations and electrical works that are required for commercial purposes must be done by registered and licensed electricians. In order to find licensed and qualified electricians, one can take the help of the electrical licensing board which is legally recognized and authorized to perform electrical works. All legally authorized electrical contractors should be accredited by a regulatory body like NAPIT. The NAPIT is the National Association of Retail Electrical Technicians which is responsible for promoting electricians in the United States. Apart from that, the American Electrical Contractor Association is another organization that provides a forum for electrical contractors, manufacturers and suppliers.
