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 homeowners/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.
Classification of electrical contractors
electrical contractors in Lexington, KY, are generally classified by three major types of work performed.
- “Outside” or “line” contractors are responsible for high-voltage power transmission and distribution lines. Line contractors build and maintain the infrastructure required to transport electricity generated at a power plant through a series of high-voltage lines and substations before it is used to power facilities, buildings, and homes.
- “Inside” electrical contractors provide electricity to any structure within a property’s boundary lines, including outdoor lighting or substations. Under current construction specification guidelines, “inside” electrical contractors can serve as prime contractors for all electrical and cabling design, installation, and maintenance for commercial, institutional, and residential buildings. Projects also include Database Centers/Infrastructure and Pharmaceutical Work.
- “Integrated building systems” (IBS) or “Voice/Data/Video” (VDV) electrical contractors work primarily with low-voltage installations such as backup power, climate controls, wireless networks, energy-efficient lighting, telecommunications, fiber optics, and security systems. IBS contractors are particularly skilled at integrating these system controls for maximum energy efficiency and building performance.
