Great video. In your conclusion section at the end of the video I would ask that you point out that even at the resistance levels you were able to obtain, 120 volts to ground would still not trip a 15 amp breaker. While code requires 25 ohms or less, it takes 8 ohms or less to trip a 15 amp breaker and clear the fault hazard. Code compliance is necessary, but safety is also very important, and faults need to clear the hazard by tripping the breaker.
