I worked for a Utility and installed the "Surge Protectors" that SECO installs. They are designed to protect your home from "voltage surges out on the line". Lightning strikes on the line, poles getting hit by vehicles, trees down on the lines and animals climbing on transformers. TV is underground but some of the underground is fed from aerial pole lines. We had a pole hit one time where a 34,000V line on the top of the pole fell into the 12,000 volt line below it. About 20 house close to where the pole was hit had their "surge protectors" blow out of the meter socket and land about 10 feet in the yard. Some of the houses had damage and some did not. You be the judge! I have SECO's surge protector and will be installing another one on the panel box when my one year warranty is up.
