About electrical contractor

An electrical contractor is a business person or firm that performs specialized construction work related to the design, installation, and maintenance of electrical systems?a $130 billion industry in the United States.1

An electrical contractor is different from an electrician; an electrician is an individual tradesman and an electrical contractor is a business person or company that employs electricians. Both usually hold licenses and insurances to properly and safely operate a business, protecting the employees and home owners/business owners from insurance liabilities. These requirements vary from state to state. Electricians may work for an electrical contractor, or directly for individuals or companies.

Worth to know - AC Power

Power in an electric circuit is the rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as active power (sometimes also called real power). The portion of power due to stored energy, which returns to the source in each cycle, is known as reactive power.

Most electrical services during the construction of the house

When it comes to houses, many electrical work is needed at the stage of construction. At the appropriate time work is carried out in respect of manual excavation in which the wires are subsequently stacked. Then, when the walls have been rebuilt there is a need to distribute the system throughout the house. He then are assembled separately, and all kinds of electrical outlets, of which the inhabitants of the house will later use. Of course, they are responsible for bringing the electrical system to the possibility of exploitation. Often electricians are also involved in installing electrical systems, such as intercom systems, which are quite useful, especially when dealing with a compact architecture.
