"As some folks have noted, to be safe and stay within accepted limits of leakage current allowed by UL and other Safety Agencies, a capacitor from Neutral to Ground is not going to be able to be much larger than a few thousand pF. It should also be an AC line rated part (in this case, a "Y" rated cap), rather than whatever is laying around in the junkbox.Your mention of 10k worth of capacitance is thus not even a good idea if you were referring to pF units.
Please note that the voltage is indeed zero (or close to it) when there is no load connected, but as soon as a load is present, now there is a voltage differential between the Neutral and the Ground wire."
Jon RischJust to add, for those reading this thread, if the house was built after 2008 there is a very good chance the breaker that protects the branch circuit wiring, the power cord is plugged into, is a AFCI (Arc Fault Circuit Interrupter). A detected leakage from the neutral conductor to the equipment grounding conductor will cause the breaker to trip open.
Edit. AFCI protection required for bedrooms 1999/2002.
