    Have a rental with UN grounded outlets. Panel box already upgraded.
    So instead of trying to pull new romex into old metal boxes I was planning on just adding a ground wire. Any tips on this?
    I was planning on just running a 12 gauge green wire ground to a double box I will put in the crawl space and then only have to fish a small ground wire to each box and then run each one back to double box and then wire nuts.
    Do I need a junction box or could I just mount one of the short ground bar clamps to a joist and use that for about 20 connections
    Thanks

    Much controversy surrounds the correct interpretation of the NEC regarding this. I recommend an Internet search with majority of opinions ruling, but give Holt's forum somewhat more credibility.

    You say you have "old metal boxes". What type of wire is run from the panel to the metal boxes? If it is BX type wire the metal cover is carrying the ground and all you would need to do is add grounded outlets and connect the ground terminal on the outlet to the box with a grounding screw and pigtail.

    It is illegal to do electrical wiring in a rental unless you are licensed.

    Its the old 2 wire romex not BX cable.
    Its Ok to do work here if you are homeowner, pull permit and pass inspection.
    I had no problem when I did that when I upgraded the panel to breakers and from 100 amp to 200 amp.
    I will let you guess what I will do just for a ground wire.
    They also require a permit to replace a water heater. But still dont know of any licensed plumbers that do that even when they dont own the home.

    Since when?

    quote; ya and a electrician is not to drill holes in studs with out a builders lic

    Where did that come from? And what jurisdiction would be dumb enough to even write such an ordinance, much less try to enforce it?

    I'll admit I sometimes wish they would....

    Plumbers, even more so.

    I don't have a code ref, but I think this can't be done. Check Mike Holt's forum (no posting though...read the rules).

    The cover of (very) old BX cannot be used as a ground since it does not have a bonding strip.

    The cover of AC which includes a bonding strip to ensure continuity can be. My 1950s AC has a bonding strip. It makes all the difference.

    Single conductor used for grounding two wire receptacles

    Correct if I am wrong, but didn't the old code books allow for such a
    thing. That you could connect to the nearest water pipe, (not plastic).
    Then it change to the grounding conductor had to be run all the way
    back to the service panel.

    I can't point to anyhing in the code that saids you can't do this.
    But I would make up my splices in a U.L listed junction box. Reason,
    all 120/240 volt circuit are splice together inside j-boxes/oulet boxes/
    switch boxes.

    If you are worry about the single conductor be damage, you could
    could install it ENT tubing. But I wouldn't, I would label it, so others
    would know what this wire is used for.

    Now will hear from the rest of the guys.

    Please note, the above is only my opinion.
