Hi all! Here's my trouble: On Cir #7, I have 4 standard 120v duplex outlets. When tested with the circuit analyzer, they are registering "OPEN GROUND". When we pulled one outlet out of the wall, blk&white wires were screwed down and the ground wire was as well (2-wire cable w/ground). Why do they register "OPEN GROUND" when tested? Could one outlet on that circuit NOT be grounded at all? What is the best way to fix the problem?
You have an open ground wire somewhere on the circuit. It could even be in the main panel. Is the entire circuit wired with 2 wire + ground cable? Sometimes people add on to existing circuits that don't have a ground.
More info: after further testing, we have found that 2 of the 4 duplex outlets do in fact APPEAR to have black,white and grd; all secured. The end does NOT have a grd same holds true for the first. Is there a method to ADD a ground to #1 and #4? I alos note #1 and #4 are in plastic boxes, not metal.
