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?
The term ‘earth bonding’ refers to the use of a thick green and yellow copper cable to connect your gas meter or consumer unit to incoming supplies such as your gas pipe. The connection is made on the metal pipes and clamped within two foot of where it enters the building.
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.
Do gas meters need to be grounded?
In general, the recommendation is that utilities should use an independent ground rod, not a gas meter. … If electrical grounding is improperly attached to an Xcel Energy gas meter, the natural gas system is no longer provided with corrosion control.
Is CSST gas line safe?
Is CSST piping safe to use in my home? CSST is safe. CSST must be installed by a qualified professional and in accordance with the manufacturer’s design and installation guide and local codes, using proper procedures to bond the piping directly to the electrical service.
How far can you run CSST gas line?
The flexible connector length usually is limited to 3 feet except for gas ranges and clothes dryers. For these appliances, 6 feet generally is allowed. Splicing or joining connectors with nipples often is prohibited.
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?
CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home.
Do you have to bond black gas pipe?
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.
Does copper gas line need to be grounded?
There are a few reasons that this is required. 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.
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.
