What is the minimum distance a metal fence must be bonded when installed near a pool?

The correct answer is based on the electrical safety regulations concerning the installation of metal fences near pools. The National Electrical Code (NEC) requires that metal fences should be bonded to prevent any potential electrical hazards. In particular, the minimum distance for bonding a metal fence around a pool is set at 5 feet. This distance is established to ensure that any stray electrical currents cannot reach the pool area, thereby reducing the risk of electrical shock to people utilizing the pool.

Having the fencing bonded at this minimum distance helps create a safe environment, as it ensures that any metallic structure is at the same electrical potential as the ground. This practice is crucial in areas that may be exposed to moisture, such as near a swimming pool, where the risk of conductive pathways increases.

Other distances provided in the choices do not meet the established safety standards necessary for proper bonding near a pool. The NEC guidelines are in place to protect individuals and ensure safe electrical installations.
