My old home (50's) has, for the main part, no ground wires running to the outlets. The wiring is romex, but, only a hot and a neutral except where I have added additional outlets. The previous owner has placed three hole (grounded) outlets on many of the two wire circuits. I know that is not to code and should be converted back to groundless plugs.
Question: Can I simply run separate ground wires to these outlets. Almost all of the wiring reaches these outlets via the attic crawl space. Do I need to make 'home runs' to each outlet or can I install splice boxes in the attic and do radial runs from therein?
All advice or criticisms appreciated.
Thanks, Ivan Vegvary
