Hi, i have just built an extension to my utility room and made it into a large kitchen, to do this i have used the existing consumer unit to supply a new ring main and lighting circuits. I have fitted a new cooker with gas supply a new sink and two radiators fed from an existing com-bi gas boiler in the corner of what was the old utility room.
What i need to know is what sort of earthing or earth bond and size of cable is required apart from the earth which is in the 2.5mm twin & earth ring main cable fed from the consumer unit.
