Wiring PS300 for Low Voltage Landscape Lighting

[Nola83]

I am trying to wire a Pentair PS300 transformer into my ET8. Do you have to wire it to a circuit with a GFCI breaker?

My gut says yes.

While I am not going to try and "guess" or "reference" code, common sense says you need it protected by GFCI protection.

My setup was similar. I wired a P300 transformer for my landscaping lights. It was plugged directly into the the pad mounted GFCI outlet, running off a dummy timer. I finally wanted it controlled via the automation system (ET4). So I wired it into its own relay and added a GFCI breaker.

This is the one I used. https://www.homedepot.com/p/Eaton-B...++786680134111+{productkey}+qu:{786680134111}
