A kitchen sink does not need to be earth bonded unless it has a metal waste pipe in contact with the earth outside. However the incoming water service should be bonded to the main earth terminal (in or near the consumer unit) with a minimum of 10mm^2 cable (16mm^2 recommended) unless both the water main and the plumbing installation are plastic.

In the bathroom bond between the bath and any metal water & heating pipes and the circuit earths of any electrical equipment which is within the defined zoned areas (zones 0 - 3). The wire size required is only 4mm^2 and this does not need to be run back to the main earth terminal (this is local supplementary bonding). If the water pipes to the bath are plastic then the bath does not need to be included in the bondng scheme unless it is in contact with metal parts of the building structure. Bear in mind the object of the exercise, which is to ensure that any metal items that you might touch simultaneously are electrically connected together. More details and example diagrams can be found in the IEE on-site guide (ISBN 0 85296 987 2).

EC14 (brass) is for dry indoor use only; EC15 (phosphor bronze) is suitable for indoor or outdoor use. Both of those accept wires between 2.5 and
