Having surge protector strips all over the house has not proven worthwhile. On the other hand, the installation of whole house surge protection has proven to be much more successful. This also takes care of switching transits cause by load balancing by the power company. As to protection for lightning, that's a totally different approach and methodology. Lightning rods installed on the house, all ground rods bonded together, copper plumbing to ground system, all services {phone, cable, TV antenna, satellite dish and etc} connected to the bonded ground system. Still if there is a direct strike, as we have received, get ready to repair and replace some stuff. Hopefully, the house is still standing. 73 Bob, K4TAX On 1/18/2019 3:43 PM, Bill Johnson wrote: > Bob, totally agree and this is exactly what I have. Main breaker box, whole > house protection.
