How far horizontally must switching devices be located from a pool unless a barrier is present?

The correct distance for switching devices to be located horizontally from the edge of a pool is 5 feet, unless a barrier is present that meets certain requirements. This specification is outlined in the National Electrical Code (NEC) Article 680, which focuses on the installation and safety requirements for electrical equipment around pools and similar installations.

The 5-foot requirement aims to enhance safety by ensuring that electrical devices are situated at a safe distance from potential water exposure and splashing that could create a hazardous situation for users. Installing switches or other control devices closer than this distance increases the risk of accidental contact with water, which could pose severe electrical shock hazards.

The presence of an appropriate barrier, such as a fence or wall, can mitigate these risks and modify the requirements, as barriers are designed to prevent unauthorized access and reduce the likelihood of people coming into close proximity to electrical devices. In the absence of such a barrier, maintaining a 5-foot distance is crucial for ensuring safety around pools, as outlined by the NEC.
