Electrical maintenance is the upkeep and preservation of equipment and systems that supply electricity to a residential, industrial or commercial building. It may be performed by the owner or manager of the site or by an outside contractor. The work is commonly performed on a schedule based on the age of the building, the complexity of the electrical system or on an as-needed basis.
The main areas of general electrical maintenance commonly include the power outlets and surge protectors, generators and lighting systems. These supply sources are checked for structural integrity as well as internal stability. The maintenance plan normally includes the regular replacement of burned out fluorescent and incandescent lights. Many building managers in recent years have refitted their lighting systems with energy saving bulbs and elements.
