Outlet is dead but ears are hot!? Whassup?

So the solenoid impedance, Z, = 123v/.0275A = 4.5 kohm.
If you measure the DC resistance then the coil reactance due to its inductance can also be figured out.

The test resistor in a GFCI is about 16k, so this will definitely trip GFCIs.

Here is a lower cost Wiiggy type tester since the name Wiigy is trademarked.http://www.lowes.com/lowes/lkn?actio...Voltage+Tester

I'm with you Bob. Wiggys thake the guesswork out of the process. Iam an hvac guy and my wiggy does not leave my belt during summer cooling season.

The main plus is that it doesn't respond to phantom voltages, and since you have some idea of what voltage is "normal" [120, 240, 460] it doesn't need to be very accurate. And it's rugged.

Many of the Electrical Plug-Iin three light testers also have a GFCI test button that connects a resistor between the Hot and ground to verify that the GFCI will trip. HF has the Tester without the GFCI Test button for $2.99 and with the Test button for $4.99.
http://www.harborfreight.com/cpi/cta...emnumber=32906

For the small increase in price the GFCI Test is worth it. For example sometimes downstream receptacles are wired off the 'Load' terminals of a GFCI and are not marked "GFCI PROTECTED" By using the GFCI Test button a user can tell whether or not a GFCI or GFCI breaker is upstream.

The best GFCI tester is still the GFCI TEST button. These work the same way in that they connect a bleed resistor to the HOT, but instead of connecting the other end through a pushbutton switch to ground the other end in connected to the Neutral before the CT. What this does is make the GFCI test button work even if there is no EGC (Equipment Grounding Conductor).

The GFCI will still trip on the current differential. The GFCI does not depend on the EGC for its on board test circuit.

For Dimmer ckts especially 3-Way dimmers the Wiggy saves the day.

MY two other most used tools are the three light receptacle GFCI Tester and this Voltage Sniffer:

This GT-16 model has an adjustable threshold that also works as an almost fool-proof on/off switch. Tracing Low voltage ckts and finding opens in outdoor lights is a real plus.

Got my first Wiggy back in 60 when I was an electrician in the Navy.

Hey, it's not often that I find the opportunity to find someone older than me.


I got my first wiggy when I was 18.

I got my fisrt voltage tester a few years after that.

Sorry I don't have the time nor the talent to explain just how far off this remark is. Z does not equal E/I !!!! and no, you cannot measure the DC resistance to find reactance...NOT! (hint: iron has something to do with the answer)
