Frequent question: What does bonding a gas line mean?

To make it really simple, when metal that can carry electricity (but shouldn’t) gets connected together to eliminate potential, we call it bonding. If the metal accidentally carries electricity or even a static charge, proper bonding will allow the electricity to be carried back to its source in a safe manner.

Does gas pipe need to be bonded?

Metal gas piping: NEC Sec. … 3.14(a) requires you to bond the aboveground portion of a metal gas piping system to a grounding electrode system for safety reasons. NFPA 54, Sec. 3.15 does not allow you to use aboveground portions of a metal gas piping system or its components as a conductor in electrical circuits.

Why is bonding of gas piping required?

The purpose of bonding interior metal piping to the building grounding system is to provide a safe electrical path to ground should the metal piping become electrically energized. This safety requirement is intended to protect the system user from shock and the gas piping system from damage.

What is a gas Bond?

What size wire do I need to bond a gas line?

The bonding conductor must not be smaller than a 6 AWG copper wire or the equivalent size if made of aluminum. The means for attaching the bonding conductor to the grounding electrode system must be in accordance with NFPA 70. The bonding conductor must be not longer than 75 feet (22,860 MM).

Does CSST gas pipe need to be grounded?

Can gas and water be bonded together?

Depending on the route of the pipes, it would be permissible to bond the water pipe (at point of entry) as normal and then connect the gas pipe (at point of entry) to the water pipe at a convenient location; i.e. to use the water pipe as the bonding conductor for the gas. The other way round is not allowed.
