What is the distance within which floor receptacles can be counted toward the required number in a dwelling unit?

The correct answer is 18 inches because the National Electrical Code (NEC) specifies that floor receptacles can be counted as part of the required receptacle outlets for dwelling units as long as they are located within 18 inches of the wall. This allowance takes into account the typical use of floor receptacles, effectively accommodating furniture placement while ensuring that accessible outlets are available in living areas.

This specific distance is established to promote convenience in access while maintaining the overall safety standards outlined in the NEC. This means that receptacles placed beyond this distance would not contribute to meeting the minimum receptacle requirements, as they may not be easily accessible or usable for common household needs. Therefore, a clear understanding of this distance is crucial for ensuring compliance with code requirements in residential settings.
