I have recently purchased a new house with an in-ground swimming pool.

There are two circuits which have GFCI breakers: a 20 A circuit for the 1 HP pool pump, and a 20 A circuit for lighting.

The lighting is fiber optic where the metal low voltage transformer enclosure is mounted behind the pool fence, 10 feet away from the edge of the pool.

The transformer is fed with 12/2 UF-B and the enclosure is bonded with the heavy green bonding wire that daisy chains around from the breaker panel to the pool pump, etc.

However, the previous homeowner added some low-voltage plastic landscape 12V floodlights around the edge of the pool, no more than 3 feet from the water’s edge.

However, he did not use a transformer specifically UL listed for use with pools and spas.

He just used the cheap transformer that came with the lights, cut the 3 prong plug off, and hard wired it into to enclosure for the fiber optic lights.

I intend to remedy this situation by replacing the old transformer with one designed for this application, the Intermatic PX300.

Question: Interpreting NEC Article 680, does this enclosure also need to be bonded, since it is 10 feet away from the water’s edge?
