![]() The ground rod is an essential part of the grounding system. 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. This is because lightning can blow holes in CSST, causing a gas leak. ![]() The bonding point for CSST must be at the first piece of steel or copper pipe where the gas service enters the home. Gas pipe in some new homes is a flexible material called corrugated stainless steel tubing (CSST). The bonding connection point for these pipes can be at any accessible location, such as at the water heater or at the gas meter. Gas pipe in older homes is usually steel or copper. In that case, correct bonding of the piping system will ensure that the current does not remain in the system, where it could electrocute anyone who touches a part of the system, such as a faucet handle.īonding is done relatively efficiently at the water heater, as the gas piping and water piping generally there. The wires that bond your metal piping are preventative, and they only become important in the unlikely event that an electrical conductor energizes the pipe.
