Ken Meyer Posted June 17, 2011 Report Share Posted June 17, 2011 Grounding wires to receptacles must run along with the conductors to those receptacles, correct? I think I remember this being discussed before. This 1950 house had a new service and panel (with permits), exterior ground rods, and a bonding wire to the copper pipes at the water heater. The bonding wire to the water heater passes through a terminal bar mounted to a floor joist, and grounding wires go from there to outlets in the basement and elsewhere. It looks to me like the electrician grandfathered in an existing situation where the outlets had been "grounded" to a water pipe, judging from the older splices and separate grounding wires to older J boxes. The water service has been replaced with PEX, so the old system of "grounding" those outlets was lost. So my question is: must grounding wires run along with the conductors in either conduit or in a cable assembly like romex?

allseason Posted June 17, 2011 Report Share Posted June 17, 2011 You need junction boxes at the exposed splices.. Quote Link to comment Share on other sites More sharing options...
Ken Meyer Posted June 17, 2011 Author Report Share Posted June 17, 2011 I think I found the answer in Code Check. "EGCs must run w/other conductors of circuit. EXC Replacing nongrounding receptacles. Separate EGC OK from box to service or ground bar of panel where circuit originates." Quote Link to comment Share on other sites More sharing options...
John Kogel Posted June 18, 2011 Report Share Posted June 18, 2011 He could have pulled new NMD to all those boxes for not much more time and money, but there's no limit to basement ingenuity. So I'm disappointed that there's no sardine can nailed up to cover that terminal bar. Quote Link to comment Share on other sites More sharing options...

They can't just be strung around like a clothes line. Quote Link to comment Share on other sites More sharing options...
