No ground wire for the 3 prong recept. Tester says open ground. I need to ground all the recepts in my house to pass inspection. What is the best and low cost fix? Thanks
"Best" and "low cost" are contradictory. The "best" would be to run the correct wire direct from the panel (as well as correctly grounding the panel if it isn't already). The only "low cost" option would be if the panel is properly grounded and there BX cable running from the panel to that receptacle. Then the box for the receptacle should be grounded by that BX and a ground wire to the box would be acceptable.
