    GFCI Breaker for Pool Lights

    Does the NEC 2017 require a gfci circuit breaker to be used to feed pool lighting circuit if the lighting system in using a NSI Industries TPX300 pool light transformer?

    The TPX300 is a step down transformer 120 primary / 14 v secondary.

    680.23 (A) 3. Says GFCI breakers to be used branch circuits supplying luminaires operating at a voltage greater than the low-voltage contact limit.

    Looking at the situation from the primary side one would say YES to the GFCI
    Looking it from the secondary side one would say NO.

    Advise

    Thanks

    The primary side needs gfci protect however I have never seen gfci protection on the secondary side. We also gfci the line and that's all one can do.

    I have never seen a GFCI made for LV. Further, because the LV secondary is prohibited from being grounded (IE it's floating), if it should fault to something there would be no risk.
