    But should trip immediately and not after 3 seconds.

    Capacitive leakage because of a long run could be an issue though.

    This sounds like a job in California, and a project with a jobsite trailer so I would assume permitted. So I would be these have 0-10v dimming being under the energy code. I would bet that this is temped in using a GFCI receptacle. There is probably a issue with current flowing back on another neutral or through the dimming.
