Just to update, wasn't clear where the cable went into the CU, its a bit of a mess. However, managed to determine the cable exited from the bottom which meant could identify the route. Put another break in the cable between the kitchen and CU and found the fault was near the CU under...

I know the breaker but the cu is a mess, I'll post a pic and hunt the earth and neutral tomorrow.

Small update. Cut the cable before the socket to see if it was bad behind the tiles and unfortunately not so the problem is further upstream. If earth is live surely it must not be correctly connected to the CU? Or is that not true. I can't see anything obviously wrong in the CU short of...

This. I was think control unit was CCU or connection unit but I should have been calling the "socket" the control unit

Cheers all. Its not the socket, I swapped it and the faceplate (metal) was live. Turned out was the earth conductor. Could be the sleeve or damaged live or fault in the CU or elsewhere in the cable.... Will check a few more things later this afternoon but all off for now. Microwave dinners it is!

Yes that's right. I double checked with the cooker handle when it was connected and my finger and that was exciting.

Earth into the socket is 240v, live is 240v.. I'm a bit mystified how either the fault could suddenly appear or it could have been wired like that for the last 20 years?

The earth conductor is live (y)

Looks like 240v from the cooker and the socket. How have I never had a decent shock Disconnected the cooker and will see if I have a spare socket to rule that out.

Annoying just lost a post as I wasn't logged in...

Cheers. Assume the socket should be on? I've got it disconnected atm

I'm n The buzz stopped when I changed the element. (it was really mild). The red light on the screwdriver doesn't light if i plug the grinder into a socket the tester says is wired correctly. If I touched my coffee machine (metal) which is on a different socket to the grinder while the grinder...

Sorry took a while to work out how to shrink photos, uploaded now!

Ok can see the cooker and socket share the same earth. I cant see anything wrong on the socket so would suggest either the cable is fooked (big problem), maybe the socket but seems a long shot, or the RCD connection?

Cheapo socket tester suggests L N reversed which is usually earth fault. Does it follow the oven is not earthed because the socket has the fault? The grinder I don't think is double insulated.
