This video show 3 different methods I use to test for an open or loose neutral in both 120v and 240v outlets- by using a regular Multimeter, a LoZ meter, and a Voltage Pen. To donate to The Tech Circuit, click here: techcircuit.org/donate

Steve, at around the 2:40 mark you show a measurement at neutral wrt ground that reads a nominal 120v. Would we have seen that reading if the nightlight wasn't plugged into the receptacle above? Great video as always. Thank you.

No you wouldn't have because there is some connection to Neutral at the breaker box, but not a very good one - through the high resistance of a loose connection. What "pulls" neutral toward L1 is the low resistance of the light bulb (as compared to that high upstream resistance on neutral). The resulting "voltage divider" favors a very low voltage drop between L1 and the outlet's Neutral slot.

@@TheTechCircuit This makes sense. Thank you for clarifying.
