I just wired up a Daikin mini-split that had two heads. When I usually install these I do not use a GFI breaker but the plumber insisted so I ordered an expensive GFI 240V breaker. The Daikin Condenser/heatpump outdoors does not have a connection for a neutral wire. I hooked up the GFI breaker, connecting factory installed neutral pigtail to the neutral bar in the panel. I left the space for the load neutral empty on the breaker since their isnt one for the unit. Before turning the disconnect on I verified 240V at the line side of disconnect, I verified 240V at the unit terminals. The unit will come on for about 3 minutes and then when the fan goes to kick on the GFI breaker trips. I am getting some mixed things about using GFI breakers with these units and am also questioning my breaker. Does anyone have any input? Maybe I should just install a standard breaker and be done with it?
