I have an old house (this old house) built in '51. All the electrical outlets are 3 prong, except in the living room where, of coarse, the Audio/Video stuff resides. The metal wall box (you should see it, thick metal painted black - nothing like todays stuff) has no ground connect & just two wires (hot & neutral). In order for a surge protector to work it needs to be connected to a 3-prong outlet. The exterior walls are block with plaster coating. Can I just drill a hole through the block from behind the outlet wall box and then drive a copper rod into the ground or does the ground on the outlet have to go back to the breaker box? I have the current 2-prong outlet being fed from a GFCI outlet as per code.
I live in Albuquerque NM. I know how to run Romex, fix it with staples 6" from outlet boxes, etc, just need to know if it will be up to snuff if I do it this way
