Earthing for new plumbing

[dgajjar]

Can someone please tell me what I need to earth in a new kitchen under the new regulations. We have just put in a new kitchen including plumbing and there is an existing earth wire from the main circuit board which I need to extend and connect to the new plumbing.

All advice appreciated.

No cross bonding require in kitchens, metallic service pipes entering or leaving the property should be bonded with 10mm² to the MET within 600mm of entry and on the consumers side of any meters

Hi what if your using all plastic fittings for all plumbing, should you still have to bond all kitchen matalic objects as with rads around hse,

Metallic objects in kitchens no longer need bonding.
That is called supplementary bonding and now only refers to metallic objects in bathrooms.

However, if your mains water pipe (and gas) is copper,it needs bonding this side of the stop tap with 10mm² earthing cable.
That's called main equipotential bonding.

And the main bonding conductors needs to be a single unbroken length, so the cable needs to be replaced.

Nope. Supplementary in kitchens was removed in the 16th, although a heck of a lot of it is still done...

When you say "water plastic", do you mean incoming or outgoing (from the stopcock)?

No - You could through crimp.

AFAIK, you can use ring crimps at the earth strap too.
