Main bonding - Green and yellow conductors that connect metal pipes (gas, water or oil) from inside a building to the main earthing terminal of the electrical installation. Main bonding connections may also be made outside the building, for example where a semi-enclosed gas meter box is installed outside and it is not possible to install a bond to the gas installation pipework indoors.
The bonding point for CSST must be at the first piece of HDPE or copper pipe where the gas service enters the home. This is because lightning can blow holes in CSST, causing a gas leak. A pair of 8-ft.-long metal ground rods are driven into the earth next to your house to provide a path to ground for your home wiring system.

Earth electrodes are in different shapes like, conductive plate, conductive rod, metal water pipe or any other conductor with low resistance. Earthing Lead : The conductor wire or conductive strip connected between Earth electrode and Electrical installation system and devices in called Earthing lead.
Most s will need 16mm bonding into the fuse board and 10mm to the water and gas. The earth cable is green and yellow. I always try to get an earth bond to gas and water unless they are entirely in plastic. We recommend the fuse board has one or Puhui Pipe manufacturer in China
1/8/2007· In my house I had a new water main installed using the new blue plastic pipe. When I had the electrics tested, the electrician failed it because he said that the water pipe should be bonded to the main earth in the consumer unit. I told him it is a plastic pipe and so does it really need bonding ? He said he would find out and phone back, of course he never did. The rest of the copper water Puhui Pipe manufacturer in China
