Pool Light Repair

[BajanAl]

Removing a 12V 300W light in order to change the bulb, I found the cable had been spliced a few feet away from the lamp assembly... and the ground wire severed. The installer says he used heat-shrink underwater connectors and that 12V lights do not need to be grounded. He said it was up to code.
Can this be true? I always thought that even a nick in the cable meant the whole light had to be changed. And if 12V lights do not need grounding, why do they come with a ground wire?

My 12V Light has a grounding wire also....and its connected through to the Transformer.

Grounding is a good Idea in any electrical system, even if it isnt required.

The 12v light will not need a ground but if it is metal it should be bonded to the housing.
