When must a receptacle outlet be installed in a residential garage?

A receptacle outlet must be installed in a residential garage to ensure that there is a convenient and safe power source available for tools, appliances, and even electric vehicles that may be charged there. According to the National Electrical Code (NEC), particularly Article 210, it is mandated that at least one receptacle outlet is provided in residential garages to promote safety and utility. This requirement is essential to support the various tasks performed in a garage, ranging from general maintenance to use of power tools.

By specifying that at least one receptacle must be present, the code helps reduce the risk of overloading circuits and encourages proper electrical practices, such as not using extension cords for permanent connections. Other choices do not align with NEC regulations, as receptacles are indeed necessary regardless of the presence of a door leading to the house or whether the garage includes a workshop.
