HS220's on new AFCI/GFCI dual function circuit breaker - tripping
I've had 2 of these switches installed in a 3-gang box for 3 years and they've worked great!! The 3 gang is at our entry, one standard dumb-switch for the foyer light, one HS220 for the front porch light and one HS220 for the garage carriage lights.
Last week we had a panel upgrade to add additional circuits to the house and a generator interlock. Along with this, many of the homes circuits were upgraded to new dual function AFCI/GFCI breakers to include the feed to this 3 gang box.
Everything worked fine until about 2 hours after the electricians left with all work completed and around the time the HS220's were to come on with their schedule, that circuit tripped. This is the only problematic circuit with the dual function breakers in the house. I tried to close the breaker and it was instantly tripping. Through process of elimination, I realized the trip occured roughly around the time those lights are to turn on.
So I removed the line side hot to both of the HS220's, effectively just removing them from the circuit, and safed them off in the box. The breaker could now close and all has been fine since except I don't have porch or garage carriage lights.
It's evident that the switches worked on this circuit for 3 years, and on the new breaker for about 2 hours, up until they were to latch the relay and turn on. I've seen other posts regarding this model downstream of a gfci outlet or gfci breaker tripping. Does anyone have newer up to date info on a fix, if any? I saw a post recommending switching the black/hot line in/out wires at each switch, but I'm uncertain if that is a true fix, or what would be different about that scenario.
All 3 switches are properly grounded, all neutrals are tied together within the box and there are no rogue circuits, just the single feed into the box, out to the three sets of fixtures.
