Ground wire question

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

Yes, as per NEC 250.134(B) exception #1. You can access the 2005 NEC online through a java applet via:

Home runs are not required. For a retrofit application like this, you could daisy chain all the equipment grounding conductors (EGC) in a single run.

id do only the ones needed, most things dont have a ground prong anyways, computer, fridge strove, washer thats probably about it. most of those have a metal shell is why they are grounded.

I have the same problems with a 50's house. Can you give more detail how to retrofit daisy chain and especially where to buy the grounding conductors (ESG).

Thanks
