Garage door operator
Comments and question. Just replaced the logic board on a Sears Craftsman (Chamberlain) operator. Apparent surge from lightning. Chamberlain offers a surge protector for the doors, their number CLSS1. I bought them for all my doors. In the package is an insert, looks like an afterthought. "CAUTION- do not install this device if there is not at least 10 meters (30 feet) or more of wire between the electrical outlet and the electrical service panel." No mention of this until one cuts open the blister package, made in China.
I know a bit about electricity, but the reason behind this escapes me. Lots of residential garages also have the electrical service panel with distances much less than 30 feet. In my case, the distance is about 25 feet.
Anyone know what is the reason for the necessary distance?
