I purchased two surge protectors and when I plugged them in at two different receptacles in my apartment, I noticed that the 'grounded' light did not illuminate on any of them.
To shorten the story, I discovered that at every single receptacle in my apartment, line and neutral were swapped! I rewired the two receptacles (just swapping line and neutral) where I am using the surge protector and it lights up all good now.
My question is, given that all the other receptacles are still reversed, should I be concerned? I mean, most devices don't care I would imagine. They just need to see a differential of 120 V. But clearly the surge protector cared, so are there any other devices that do care?
Also, another question. I have a dsl modem with a telephone cable that does not go through the surge protector. My Xbox has its Ethernet cable connected to that dsl modem which also functions as a router. Is it possible that a surge could go through the telephone wire, then through the Ethernet all the way to my Xbox and damage it?
