Can I ground to a gas pipe?
Can I ground to a gas pipe?
In summary, you cannot use a metal underground gas piping system as a grounding electrode. However, you must bond the piping system to the grounding electrode system for safety reasons.
Should a natural gas line be grounded?
3 Answers. According to National Electrical Code, the pipe has to be bonded. However, it can be bonded using the grounding conductor serving the equipment that uses the gas.
What is the best pipe to use for underground gas line?
The material of choice for most above ground installations of natural gas piping is ASTM A53/A53M, black steel, Schedule 40, Type E or S, Grade B. carbon steel pipe.
How much does it cost to ground a gas line?
it should cost less than $20 for the materials. If you hire a contractor it would cost $60 to $100.
What is the difference between bonding and grounding?
Bonding is the connection of non-current-carrying conductive elements like enclosures and structures. Grounding is the attachment of bonded systems to the earth. Both are necessary to safeguard people and property from electric hazards.
Does copper gas line need to be grounded?
Grounding means connection of a copper wire, often bare copper – to your gas line, then connecting the other end to your homes grounding system. National Electrical Code requires all homes to have a grounding system. This system consists of a ground rod (8′) driven in the ground close to your electric meter.
Why do you need to ground a gas line?
Systems that are made up of black iron (steel) pipe are bonded to prevent electrical shock in case the pipe comes into contact with an electrical circuit. But, the newer yellow corrugated stainless steel tubing needs to also be grounded to prevent it from exploding if struck by lightning.
Why do you need to bond a gas line?
Bonding is required to prevent a possible electric shock hazard for persons that may be in contact with the gas piping and other grounded metallic building components. A stock hazard can result if these systems are energized at different levels of electrical potential.
Is the gas line bonded to the water line?
the Gas line is “bonded” to the water pipe “grounding” system—-in addition there may have been ground rods as well. There is the ground for the exterior ground rod. The gas ground is not for bonding. They are using for the water line ground.
Do you have to ground the gas line?
Larry the bonding of the gas piping is required “house side” of the meter because the pipe from the meter to the street is typically plastic. The gas piping isn’t a grounding system it is a metallic “system” within the home that needs to be bonded to the grounding system.
Is there ground at the main water line?
As you can see there was a ground at the main water line. I personnaly would think you would have a better ground at the water line since it is 6feet instead of 3 feet for the gas. Also home has no AFCI at the main box. Home was probably built before the 2002 code came out. Would you recommend as an improvement to add to the box? One more question.
Why is gas piping used in grounding system?
The reason in the event of a ground fault electrical energy is transferred through the grounding system which could create a spark or heat that might ignite the gas. Due to the fact that most underground piping systems are no longer metal, some AHJ do want to see the gas piping used as part of a grounding electrode system.

Can you use gas piping as a grounding conductor?
Your gas piping is effectively grounded through any electricly fed appliance (furnace) through the circuit grounding conductor. If your area requires it you would use a #6 copper conductor. The NYS Residential Code book (NYSRBC) says gas piping SHALL NOT be used as a grounding electrode.
