Megger Testing Home Appliance

[W@ttson]

Has anyone ever megger tested a home toaster oven, vacuum cleaner, washing machine, or any other home appliance that is causing a GFCI to trip but you know it’s not the GFCI but it is the device?

I’m planning to do it and set my 1587 to 100V test voltage just to be safe but then started to think, how will this interact with some of the electronics in the device?

If there are any electronics the megger will smoke those.

Megging in this case wont do you any good. You already know, but then again if it’s already broken, why worry.

I made up a pigtail so I could insert an inline amp meter in the EG of items that trip the GFCI. I clamp an amp meter on it first to make sure it isn’t sending 15 amps down the EG.
