installing Under Counter Oven

As I understand it, you have to bond the gas pipe to the main earthing terminal in or near your Consumer Unit, using a seperate cable. Your oven should be connected to your consumer unit with three core cable, one of them being earth - does the oven have a plug on the end, or is it hard wired?

Is this hob plugged into a standard socket (for the ingiter)? if so, this should be providing all the earth it needs.

Assuming this isn't a troll - NO! The earthing of the double oven should be to the earth conductor (CPC) of the cable feeding it. No 'bonding' to other metalwork in the kitchen is required by the regulations.

The cable feeding the oven space only has two wires ( no earth). hence my concern about finding an alternative earth. THe gas hob needs to be wired up . Its in a new house, which i moved into last week. thanks dave

In that case you need to get the electricians back to fix it. The supply is not usable without an integral earth conductor. You can't earth it any other way.

Get them to do that too.

Then that is what needs fixing, run a proper cable back to the consumer unit.

Where did this gas hob come into the act? I'd expect that to be able to be plugged into a standard 13 amp socket.

'New' as in really new or just new to you? If it's really a new house then go and shout at the builder about the wiring for the oven.

I got the oven and gas hob installed. There was an integral earth conductor as part of the supply to the oven space, which I didn't see straight off. Thanks a lot for your help Dave
