This is probably too silly of a question to ask in one of the actual engineering forums so i threw it here. How can I tell if my outlets are grounded? I finally got a decent surge protector and when I plugged everything in, the little light that says "Not grounded" came on :(. I checked all the outlets in that set of 4 outlets and none of them looked grounded. How can I check? I have this lil multimeter from radioshack I got long ago that's rated 500V max, 200mA max which i doubt should be used haha. Maybe my surge protector is defective.. hmmmmmm!
