You can use one of these too-
I have them installed in my main house and all my immediate family's homes, and on my camping lot on a free standing electric pedestal which supplies all our campers. Good for indoor/outdoor use.
Took a lighting strike nearby 3 years ago in a bad storm, and all the neighbor's homes electronics blew out but not anything on our camping lot with one of these hooked up.
The unit itself did blow it out, but nothing beyond that. It did its job, and it was a simple $80 replacement. You can find these on eBay and other places for under $100, and really easy to install.
Plus, it comes with a warranty and guarantee.
I'm pretty savvy with electrical and know many other master electricians who use these and they have worked well for the past 15 years or so.
