Family member's TV got smoked by a surge. Was plugged into a surge protector from probably the 1990s.

Thing is, they'll keep on supplying power but have no capacity to absorb a surge once those MOVs are done.

If you have a lot of high end electronics, you probably should have a whole home surge protector by now. Probably wouldn't hurt to check on the old folks and save them from having to buy a new TV.

Also, they do not stop a lightning strike.

And now the NEC has made whole-house surge protectors code for all new construction and rewires. On average, a quality whole-house surge protector only lasts 3 to 5 years

Have fun replacing that when needed with electricians acting like they need to charge brain surgeon rates

They aren't hard to replace, but not a lot of people are not mechanically inclined, nor do a lot of people feel comfortable working around the breaker panel

I bought one for a remodel a few months ago and just the surge protector alone was $225.

Electricians are charging around $600-$800 to install or replace them. It's so profitable for electricians that around here they are running radio ads to target people needing a new one or one replaced.

It's less than an hour install

Paying that much to have it routinely replaced is my problem with the whole situation. I realize it's cheaper than a new fridge, but still.

Do they really protect against lightning strikes though? In the 90s dealing with external antennae, I was trained that the only real protection was a big fiber filament (I think it was a foot long, for sure not an inch) that would melt if struck, and not permit the surge to "jump" the optical fuse.

A few years ago had a surge happen that blew out a couple split AC boards, fans, and totally blew up my EV charger. Got the utility to pay for it after some back and forth. Put in a whole home surge protector and of course have surge protectors that my TVs and electronics are plugged into. Mine has a green light so as long as thats on I'm not replacing the whole home.
