Outlets serving pool motors on branch circuits rated above 150V to ground and 60A or less must have what type of protection?

The correct answer highlights the requirement for specific pool motor outlets to have a Ground Fault Circuit Interrupter (GFCI) protection, particularly a special type known as a Special Purpose Ground Fault Circuit Interrupter (SPGFCI). This is designed for equipment used in pool installations, which are often subject to higher levels of moisture and potential electrical hazards due to their location and operation.

The National Electrical Code (NEC) emphasizes the importance of GFCI protection for circuits associated with pools, as this significantly reduces the risk of electrical shock. While a standard GFCI could provide protection, the SPGFCI is tailored to handle the unique electrical characteristics and operational requirements of pool motors, maintaining safety while allowing for efficient performance.

Standard GFCIs might not meet the necessary specifications for larger equipment such as pool motors operating on higher voltage branch circuits, which is why the SPGFCI is mandated in these scenarios. This ensures that both life safety and equipment integrity are prioritized in residential and commercial pool applications. Therefore, having SPGFCI protection in these systems is essential for adequate safety measures and compliance with the NEC.
