According to NEC regulations, when must receptacles be installed on a peninsula?

When its long edge is at least 12 inches
When its long edge is at least 24 inches
When its short edge is at least 24 inches
When its dimension is less than 12 inches

The correct answer is: When its long edge is at least 24 inches

Receptacles must be installed on a peninsula when its long edge is at least 24 inches, as per NEC regulations. This requirement is grounded in safety and functionality, ensuring that electrical access is available where it is needed, particularly in kitchen areas where peninsulas are commonly found. When a peninsula has a long edge of 24 inches or more, it is considered to be a distinct workspace where appliances and tools may be used, necessitating the installation of receptacles to provide power safely and conveniently. This helps prevent the use of extension cords, which can pose safety hazards due to the potential for tripping, electrical overload, or fire. The other measurements provided do not meet the NEC standards. For example, a long edge of 12 inches does not qualify for receptacle installation because it does not fulfill the criteria set for adequate work space. Similarly, the short edge measurement is not relevant under the NEC guidelines concerning receptacle placement on peninsulas.
