"...There have been reports of surge protector failures in the field.
Our investigation concluded that moisture can penetrate the unit
causing an electrical issue and potential failure. There is currently
no government recall of the surge protectors, but as a precaution, we
are removing and replacing all the surge protectors in question. There
is no additional cost to our customers."

Happy landing

We always used the Square D units. Never had a failure. ^_^

Mine hasn't failed for AC. I think it is inside the disconnect box (I
can check). Not much rain in the desert -- 4" per year.

I do plan to use a Square whole house SPD in the breaker panel
(round-to-it).
