South Carolina Long Term Health Care Administrator Practice Test

How far apart should duplex receptacles for general use be installed in corridors?

1. 25 feet

2. 30 feet

3. 50 feet

4. 75 feet

The correct answer is: 50 feet

The correct distance for installing duplex receptacles in corridors, which is established by the National Electrical Code (NEC), is 50 feet apart. This distance is designed to ensure that electrical outlets are readily accessible for plug-in devices, which helps promote safety and convenience in areas where people may need quick access to power sources. By spacing the receptacles 50 feet apart, the code aims to prevent the need for long extension cords, which can pose safety hazards and increase the risk of tripping or electrical fires. The specific distance also reflects a compromise between accessibility and practicality, ensuring that the outlets are sufficiently spaced for general use while remaining practical for the layout of the corridor. Other distances mentioned in the options, such as 25, 30, and 75 feet, do not conform to the standards set forth in the NEC for safe and effective electrical installations in corridors.
