I checked a few receptacles today for bootleg grounding in a 1974 home and found a few as seen on the pictures. I even got a 120 reading when checked the screw just for the heck of it (second pic). I also checked the range and dryer receptacles. As expected, I got the 240 v. reading when I checked the 2 lines and 120 v. when checked seperatly with the neutral. Where it gets interresting is, I also got a 120 v. reading when I checked the lines with the ground. Now, the way to get this reading is if the ground conductor is bonded with the neutral in the panel or, the receptacles were previously wired using 3 wire cables and someone changed the receptacle to accomodate newer ranges and bootleged the ground. The issue that I have with this is that the appliance's body, being most likely bonded, could get energized if a voltage surge occurs and would pose a serious risk of electric shock. (same concerns on any bootleged 120 v. outlets). What about you guys, what do you think of the energized ground on the 240 volts receptacles?
