NEC Commercial Electrical Practice Test

What is the maximum distance from a wall that floor receptacles can be located to be counted?

1. 12 inches

2. 18 inches

3. 24 inches

4. 30 inches

The correct answer is: 18 inches

The maximum distance from a wall that floor receptacles can be located to be counted is 18 inches. This requirement aligns with the National Electrical Code (NEC) guidelines, which facilitate an adequate provision of electrical receptacles in commercial and residential spaces. Having floor receptacles within this distance is strategically important as it ensures effective accessibility to power where it is needed, without the necessity of long extension cords that can pose safety hazards. This guideline also promotes the use of floor receptacles in areas such as offices or conference rooms, where furniture placement may inhibit access to wall-mounted outlets. On the other hand, distances beyond 18 inches do not count towards the receptacle placement requirements, as it reduces their practical availability and usability based on typical configurations and the need for convenience in accessing electrical power.
