I've sent you a PM to discuss this more at length off-line.I think it's a matter of semantics, so I'm working on new terminology that will allow all of us to better understand and discuss what we mean by the catch-all phrase - Ground Loops.Mike Sokol
That's true, but I'm talking about real-world situations where there are nearly ALWAYS some other current draw on a sub-panel or branch circuit. You'll only read zero volts between Ground and Neutral if there are no other current loads in those legs, or if you're on a home-run back to the...
Well, I do believe it was a problem with the guitar amp plugged into an improperly grounded outlet or extension cord. And yes, if he grabbed a grounded SM58 mic he wouldn't be able to let go. And here's why. Your body with wet hands has about 1,000 ohms resistance. Now, if you have 120 volts...
Also correct. You can meter between H-N (120-volts), H-G (120-volts) and G-N (approx 0-volts) and an RPBG outlet will measure correctly. Interestingly, one hint that a bootleg ground was done is when G to N measures exactly zero volts with a load on the outlet. Since there's always a voltage...
Mike NYou're 100% correct. I've recently found an outlet in my house that was "upgraded" in the 80's with a bootleg ground. But since my house was built in 1926 with K&T (Knob & Tube) wiring, the electrician accidentally swapped the Hot (120-volts to earth potential) and Neutral (0-volts to...
Guys, I'm Mike Sokol - The guy who created the RPBG (Reverse Polarity Bootleg Ground) video you just mentioned. I've known about this mis-wiring condition for about 40 years, but never really thought about it too much until I tried to design my own high-current 3-light outlet tester using 100...
