Small voltage running through casing of microwave and kettle that gives a shock

Probably the socket is not securely earthed, so the casings start to float.

Or worse, possibly there's some leakage between earth and live in the socket in addition. Either way, not a happy situation

Is/are the socket/s on an RCD?, what are you standing on at the problem socket? i.e. is the floor construction earthenware tiles, rugs or other electrically insulated flooring. How do you get the feeling: - e.g.hand on appliance and hand on kitchen top; or hand on appliance, other hand not touching any metalwork. Maybe you should be buying appliances to suit your user name!. Jaymack

You have a socket without an earth. Fix that, *priority*.

In this case the metal case will be roughly at 110v AC with a fairly high impedance, via the RFI filtering.

With RFI filters there ALWAYS is...and all microwaves have fairly massive ones.

but since both appliances play with water and electricity, that could change to 240 and low impedance.

Which is why I said "Fix that, *priority*."

Cordless Crazy formulated the question :

Two possibilities:-

1. The socket lacks an earth and what you feel is the normal leakage from the appliance to earth.
2. The socket and appliances are properly earthed and you are 'live'. In other words you are standing on or touching something else which is at least to some extent 'live'.

i know :) we all know
