The receptacle outlet required for indoor electrical service equipment shall not be required to be installed for which dwelling type?

• A. One-family dwellings
• B. Two-family dwellings
• C. One- and two-family dwellings
• D. Multifamily dwellings

Answer: (C)

The idea behind this rule is to provide a convenient receptacle near indoor service equipment to aid servicing and testing of the service setup. The code does not require this outlet in smaller, simpler homes, but it does in larger configurations where service equipment may be centralized or serve multiple units. One- and two-family dwellings typically have service equipment located within the dwelling in a readily accessible spot, so an extra dedicated receptacle is not required. In multifamily dwellings, with centralized or shared service equipment, having a receptacle nearby facilitates maintenance without running cords across spaces. So, the requirement does not apply to one- and two-family dwellings.
