If I have 5 old outlets that are not grounded(but installed in old plaster walls that I dont want to disturb) can I wire a gfi at lead of circuit and protect the others downstream. I have access to 1 of the outlets, and can reach the wiring of the others from under the house.Or should I fish new wire through the walls ?



You can protect the downstream receptacles, by supplying them from the LOAD side of a GFCI device.

Or you could install new cable.

  • Could you please give a code reference that allow the change of a two wire with no ground receptacle too a three wire grounder receptacle. – WarLoki Aug 20 '15 at 14:19
  • @WarLoki 406.4(D)(2)(b) and (c). – Tester101 Aug 20 '15 at 15:16
  • @Tester101 This is permitted as long as you label the non grounded outlets with the "no equipment ground" label that comes provided with most GFCI outlets. – Kris Aug 20 '15 at 16:54
  • @Kris That's true, technically. unfortunately it is almost never done in a residential situation, especially by DIY Electricians. – Tester101 Aug 20 '15 at 16:59
  • @Tester101 I agree with you about the code, but that label has got to be there. – WarLoki Aug 21 '15 at 0:33
