A question if I may

Plugged the granny cable from my Leaf intro an external socket in a house I was visiting on Saturday and when opening the car got a pretty decent buzz off the door handle.

Checked out the socket, earth wire broken, fixed it and all ok.

However am curious as to what caused the buzz because the earth was broken.

Does it point to something wrong with the granny cable rig?

Its a sealed plug..

Thanks as always

Probably leakage, there will always be some, it could probably even be micro amps. No insulation is ever perfect. It would need to go above 30mA before it would trip the RCD. There was no path back to earth for the leakage.

I'll add that the leakage was likely trying to take the path to earth via your hand, but the ground condition (wet ground, shoe type, relative humidity…) was also limiting the current which could possibly pass.

I'd say they earthed it fairly well tbh, hence the pretty decent buzz🙂

Reminds me of the earthing strips people put on the back of cars years ago to stop getting a bit of static.
