I didn't do it, because I have a friend who is a licensed electrician, who did it when he wired my house. Over time, I've picked up a lot of basics, but I like to leave the electrical box to the pros. Having said that, this device looked super easy to install, and in hindsight, with the knowledge I have now, if I were to do it now, I'd do it myself and not bother my friend. Given your background, you should be able to do it. When you buy the unit, you'll be able to tell if it's something you can do. Mine's called an Intermatic Panelguard. Dunno how well it works, but in the 8 years I've had my home, nothing's ever gone out due to surges that I can tell, and I've got tons of electronics, as is the norm nowadays.Did you install yourself? If so, how easy? If not, how much for electrician to come out and do it? I was a laborer for an electrician/ hvac company when I put myself through college and pick up some basic skills. Is this something only a pro should attempt?
