I have a house with 2-wire receptacles. From one of the 2-wire receptacles,
I want to run a line to a new 2-wire receptacle that I am adding. The wire
I have to run the line is 12/2.

The question I have is, "What do I do with the bare ground wire in the 12/2
wire?"

The original 2-wire receptacle box and the new 2-wire receptacle box are
metal. I am assuming that I should NOT connect the bare ground wire to the
metal box on either end.

Is that correct, or am I supposed to attach the bare ground wire to each
metal receptacle box even though I don't know if either box is grounded?

Thanks.



If your 2-wire electrical outlet is allowable, then just fold back the
unused ground wire. Do not install a 3-hole outlet if it is not
properly grounded. However since this is a safety issue, it would be
a very good investment and wise to upgrade all 2-wire outlets to
grounded outlets.
