What type of circuit interrupter is typically required for receptacles near swimming pools?

The appropriate choice for circuit interrupters required for receptacles near swimming pools is a Class A GFCI. Class A GFCIs are specifically designed to provide protection against ground faults for circuits that power equipment and electrical receptacles in locations where there is a higher risk of electric shock, such as swimming pools.

This type of GFCI is rated for a current differential as low as 4 to 6 milliamperes, which enhances safety by quickly interrupting the circuit if it detects a ground fault. The sensitive detection limit is critical in wet environments, where the risk of electrical hazards is significantly heightened due to the presence of water. Ensuring that receptacles within a certain proximity to swimming pools or other bodies of water are protected by Class A GFCIs is in alignment with safety standards and regulations to prevent accidents and protect individuals using the pool area.

Other types of GFCI and RCD options mentioned are not suitable for this specific application, as they may not offer the same level of protection or be designed for environments with such considerations.
