I want to upgrade the plugs to ground type in a house built in the 1960's.The old romex has a reduced size (#16 I think)grounding conductor in the cable that is wraped around the romex and pinched in the connector or under the clamp of the metal box.
What is the correct way to convert to ground type plugs in this case?
Is the reduced size ground wire in the romex OK to use for grounding?
shortcircuit
