What is the minimum voltage requirement for a receptacle near an indoor spa?

The minimum voltage requirement for a receptacle near an indoor spa is set to ensure safety and compliance with electrical standards. A receptacle rated at 125 V ensures that it can accommodate standard household electrical devices while also providing a level of protection against electric shock in areas where water is present.

This voltage requirement takes into account the specific needs of equipment that may be used in proximity to a spa, such as pumps, heaters, and other electrical components that help maintain the spa's operation. It also aligns with the National Electrical Code (NEC) guidelines, which emphasize the importance of providing adequate voltage and safety measures in wet locations.

Higher voltages could pose an increased risk of electrical shock, so the standard establishes 125 V as the suitable compromise between functionality and safety.
