Well it looks like I have quite a few jobs this year for Christmas decorations.Just curious what some of you may have wired.One job I have this year is erect and power a 50' artificial tree.The total connected load is about 50 amps @ 120 volt.The customer has a 3 phase 5 wire circuit available to use.So I was thinking of using that and a contactor to provide on-off switching for tree lighting ceremony.The question is do I need a gfci.Well who am I kidding of course I need a gfci.Is there a way to wire the gfci to just trip the coil circuit.Anybody got any ideas??
