The branch circuit conductors are 12AWG, yes? 20A breaker is fine.
Are you seeing something I'm not? The table above the one for breakers is for fuses. The 30 amp contactor says max 30 amp fuse.
That specific Square D chart is concerning the Short Circuit Current Rating of the contactor, not its full load protection.Interesting that if I use fuses I am not limited.
ActionDave, yes the condutors are #12 AWG. I am not saying you are wrong, I just want to understand why 20A breaker is ok. Because if we put 20A breaker, then it will let 20A current pass through it and it will blow the photocell because the maximum current carrying capacity of the photocell is 17.5A which is less than 20A.
