I want to install an electric oven but am not sure if this is possible as my house wiring is what i think they cal '2 core wiring' there is no earth wire. Can anyone advise if this is possible. I have a socket and an old type seperate cable socket for what must have been aprevious electric cooker connection. Really would appreciate a reply as i only habe a few days to secure the purchase of the oven at a good price! Thanks sb
