Hi,

A customer called to say she has experienced small shocks from three different light switches in her house.

The hall, the lounge and the kitchen.

This has happened on three occasions over the last couple of days.

I said, I assume they are metal faceplates...

Nope, 100% plastic...

Ok, so I said, well I am firstly not concerned as to my knowledge a Class II fitting is that for a reason and plastic doesn't conduct electricity.

I said are you sure it wasn't static? I asked is they had new slippers or shoes? new carpets etc? different clothes?

They said no, nothings changed.

I said, well ill pop round on Wednesday to take a look, but doubt ill be able to find anything as they are all plastic.

Any thoughts on this? I cant see how its possible.

She hadn't got wet hands either, switches has not got wet on them, all dry, 10 year old house too, nothing untoward.

I went round there last week to swap a couple of toilet fans, but thats it, house is in good order.

Just looking for any thoughts on what she may be experiencing?
 
I’ve had this before. Got the testers out and tested between the plastic and earth and got +50V. If I hadn’t seen it with my own eyes, I wouldn’t have believed it. Anyways, just replaced the switches and everything was fine.
