Surge Protection | Electrical | This Old House - 1
i found this article abt surge suppression. they tell u the standard to look for and why u take a multi layer approach. currently standard is UL 1449 rev 3.
in their approach, the line suppressor knocks it down to what a suppressor at the sensitive equipment can handle.
the item i had been toying with is the eaton whole house version Complete Home Surge Protection-CHSPT2MICRO at The Home Depot
what u will need will be a couple vacant slots in ur breaker box. for me. that means i will have to either mount a sub box and handle the large cord or change some of the breakers to doubles to give the two dedicated slots needed. u will have to wire to them with #14 wire.
if u read the article, the concern (that i had) abt the near by lightning strike was a problem if it was within a mile. if u get a direct hit, i doubt anything will protect u.
this will give u an alternative to look into.
i don't know if home depot handles them but eaton also offers a version that simply plugs into the breaker slots. cost abt $15 more.
last year, when i looked into this device, it was out of stock. they are in in stock now but u have to order them. home depot had the best price and free shipping. u can find this same item on the internet for anywhere from $30 more to $200 more.
