I have a basement remodel in progress...my father in law (who is an electrician, actually used to be, now 80 years old), anyways...he helped me install a secondary 60 amp sub panel to feed the entire basement. The secondary panel is a GE panel. My circuits are all 20 amp with 12/2...yes I know, he likes overkill. Anyways...I want to install a whole panel surge...but he/I am not 100% clear how this would work. I've found one that fits my box AC Power Surge Protector - GE PLUGIN - Product Information My question is this...If I am ONLY concerned about protecting circuits on the SUB PANEL is this all I need. Meaning I install this in two open "bays" in the panel, connect it up and now the ENTIRE Sub Panel is protected ? I've read that someone told me I have to install this first in line, meaning it has to be in the first two open bays in the panel ? This makes no sense as everything is interconnected... Or do I have to somehow get a different surge that connects via the incoming 220's coming off the main panel (hope I explained this properly) Hopefully I've addressed everything...any more details just ask!
