How do regulations differ for in-ground versus above-ground pools?

The choice indicating that specific installation and bonding requirements vary is correct because the regulations for in-ground and above-ground pools in the National Electrical Code (NEC) take into account the different installation characteristics and safety considerations for each type of pool.

In-ground pools, due to their permanent nature, are subject to stricter bonding and grounding requirements to ensure that all components, such as the pool structure, metal fittings, and electrical components, are properly bonded to prevent electrical shocks. The NEC specifies that all conductive materials associated with the pool must be connected to the grounding system.

On the other hand, above-ground pools typically have different safety measures. Their components may not require as extensive bonding due to the fact that they can be taken down and are generally considered less permanent structures. However, they still must adhere to certain electrical safety standards, including ensuring that above-ground metal parts are bonded as well, but the specifics can vary.

This differentiation in bonding and installation regulations reflects the unique safety concerns and risk assessments related to the different physical structures and usage of in-ground versus above-ground pools.
