Which one of the following does NOT need to be bonded in a swimming pool area?

In a swimming pool area, bonding refers to the process of connecting various conductive materials to create a uniform electrical potential, reducing the risk of electrical shock. Among the options provided, the metal towel rack is not considered a critical component that requires bonding under typical electrical safety standards.

The other items listed—such as the stairway, electrical enclosure, and pool light—are more directly associated with the electrical system or potential hazards in and around the pool. Bonding these elements helps to ensure that they are at the same electrical potential, therefore minimizing the risk of stray voltage, which can pose a danger to individuals using the pool area.

The stairway and pool light are in close proximity to water, which increases the risk of electrical shock. The electrical enclosure houses electrical components that can be hazardous, necessitating its bonding for safety. While a towel rack may be metal and therefore conductive, it typically does not present the same level of risk as the other components, and thus does not require bonding according to standard practices.

Understanding the requirements for bonding various components in a swimming pool area is essential for maintaining safety and compliance with electrical codes.
