Electrical contractors 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.
