What size wire do you need to bond a gas line?
6 AWG
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).
Can you ground a gas line to a ground rod?
It is a prohibited practice to use the gas piping as the grounding electrode and/or the grounding electrode conductor for the electrical system. In other words, the gas piping cannot be used as the primary connection from the electrical panel to the ground-rod, and the gas piping cannot be used as the system ground.
Why is gas piping bonded to ground?
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 difference between grounding and bonding?
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.
Do gas lines need to be grounded?
CSST Gas Lines Must Be Grounded Introduced in the US in 1990, CSST has been installed in millions of buildings. Since 2009, US building codes have required CSST to be bonded and grounded for safety, but that was not required during the first 18 years.
Does flexible gas line need to be grounded?
CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home. The most common issue that home inspectors find is the CSST system is not being properly bonded.
How do you ground a residential gas line?
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.
Should a gas line be grounded?
CSST Gas Lines Must Be Grounded Since 2009, US building codes have required CSST to be bonded and grounded for safety, but that was not required during the first 18 years. The reason for this safety precaution is that a nearby lightning strike could cause the systems in your structure to become electrically energized.
Can you use a gas line as a ground?
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?
CSST Gas Lines Must Be Grounded Since 2009, US building codes have required CSST to be bonded and grounded for safety, but that was not required during the first 18 years. If you have CSST in your home and gas supply line work was done there since 1990, you need to be sure it is safe.
What is the purpose of grounding and bonding gas pipe?
Grounding and Bonding of Gas Piping. The grounding conductor is the one used to connect noncurrent-carrying metal parts of equipment, raceways, and other enclosures to the system grounded conductor, the grounding electrode, or both, at the service equipment or at the source of a separately derived system.
What does bonding a gas line mean?
If you’re not familiar with the term, bonding gas lines is simply the process of attaching a grounding wire to the lines to keep them from holding a charge. You’ll often see this with the metal gas lines that connect to the gas meter, many of which will have a green ground wire looped up and connected to a fitting attached to the pipe.
Can a gas line be used as a grounding electrode?
A gas line may _not_ be used as a grounding electrode, grounding electrode conductor, or equipment grounding conductor. This means that you can’t use the pipe to ground your electrical system, but must have proper ground rods, etc.
Can You bond ground wires to gas lines?
In many areas, adding ground wires to gas lines isn’t an issue. There are some localities where ordinances might prohibit the practice, however. In other cases, bonding may be limited to situations where there is a specific threat of short and disallowed at other times.
