ANSWER: Yes, I said metal gas piping should be bonded to the supply system grounded conductor. Section 250-104(b) does require that metal gas piping should be bonded to the grounding electrode system. This can be done by terminating at the neutral bar, or any of the electrodes in the grounding electrode system..
Beside this, why do you need to bond a gas line?
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.
One may also ask, can gas and water be bonded together? the main bond has to be a continuous unbroken link. Its ok to link gas and water with the same cable but it has to be continuous. Putting an earth block in and then seperate links is like supplying 2 main earth terminals and will cause confusion later and as a spark of 20 years there no way i would do it.
Also to know is, how much does it cost to bond a gas line?
Go to Lowes to get the two clamps and the bonding wire. it should cost less than $20 for the materials. If you hire a contractor it would cost $60 to $100.
What is the purpose of bonding gas and water pipes together?
The current will always take the easiest path to ground; the idea of Main Bonding (and Supplementary Bonding) is to create an alternative path for the current to flow that is an easier path than along one of your heating pipes, along your arm, through your body, down your legs to the wet kitchen floor and to ground.

How do you ground a gas pipe?
To ground the natural gas pipes of a home or building, the Electric Connection uses grounding equipment on the home's or building's wiring. The neutral wire is conducted deep into the soil in order to disperse energy from a lightning strike. Gas pipes are not directly grounded, but they can be bonded.What is gas pipe bonding?
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 earth bonding to gas meter?
Main equipotential bonding (sometimes known as 'electrical cross bonding') is the connection between the consumer earth point and the gas installation pipe.Can you ground electrical to gas line?
The answer is no. You can't use the gas line as the grounding electrode and some other means should be verifyable - ground rod, metal underground water pipe, Ufer, or ground ring. If no other means could be verified, it should be reported as such.Does a gas water heater need to be grounded?
The water heater creates a break between the cold water pipes and the hot water pipes in the home. Note that a plumbing system with PEX or other forms of plastic water supply pipe does not require any kind of electrical grounding.Do you need to earth gas pipe?
The Gas pipe work requires to BE BONDED not to be the earth bonding. The equipotential bonding should be a max of 600mm from the gas meter or as close as possible if this distance is not possible and before any branch. The gas pipe work must not be used as an earth conductor to Ground/earth.Do you need to ground water pipe?
The NEC requires that water pipes be bonded to ground, even if these metal pipes are not used as part of the grounding system.Can flexible gas line be used outside?
Csst is suitable for outdoor use. The outer jack is uv resistant and flame resistant. Tubing must be protected from contact with sharp objects including metal cabinet edges or metal studs edges. Do not bend the pipe too much.Does black gas pipe need to be grounded?
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. As for lightning strikes, the gas company is probably correct. It's not likely lightning will strike the pipe, especially since it's right next to a house.Can you bury home flex gas line?
HOME- FLEX Underground PE gas pipe is iron pipe size (IPS). It is approved for use with Natural Gas or LP gas. HOME-FLEX Underground fittings are approved for direct burial. They can be installed without the need for special tools or equipment.Where can flexible gas line be used?
Flexible connectors may not be permitted on gas furnaces, water heaters, space heaters, etc. In areas prone to earthquake, flexible connectors are more likely to be used on all appliances since they provide some measure of protection against gas piping leakage or rupture during an earthquake.How much does it cost to bond CSST?
It varies. The cost varies greatly based on several factors: distance to the homes bonding rod and access to easily run the wire. In our experience, bonding CSST has cost as little as $256 or as much as $650.What size are bonding conductors?
For example, where the meter tail (the line conductor) has a csa of 25 mm2, the minimum size for the main protective bonding conductor (copper) must be 10 mm2. In many ways, determining the size of the main protective bonding conductors in a TN-C-S system is much simpler.What is the yellow gas line called?
The gas piping is known as corrugated stainless steel tubing, or “yellow CSST.” CSST is a flexible, stainless steel pipe used to supply natural gas and propane in residential, commercial and industrial structures.What type of pipe is used for propane?
The propane yard line generally consists of copper tubing or plastic polyethylene piping. The service piping needs to be installed correctly and legally in conjunction with the propane tank for the entire outside portion of the installation to be safe and serviceable.Can you use flex pipe for gas?
HOME-FLEX Corrugated Stainless Steel Tubing or CSST is great for installation of gas appliances. CSST easily snakes into attic and basements areas, around corners and bends, and through walls. Much easier to work than steel pipe, uses fewer fittings, and weighs a lot less too.Where do I bond gas line CSST?
The bonding conductor must be attached to the CSST gas piping system downstream of the point of delivery (either the natural gas meter or the LP 2nd stage regulator). The bonding clamp can be located at any location within the piping system. In general, the shortest bonding conductor will be the most effective.How much does electrical bonding cost?
As with other contractor bonds, an electrical contractor bond is priced as a percentage of the total bond amount required by the licensing authority. This percentage can range from 1 to 5% for most licensed electricians. As an example, a $10,000 bond with a rate of 3% costs you $300.Does Csst need to be bonded?
CSST needs to be bonded. When CSST is installed without being properly bonded to current standards, there is an increased risk for damage to the material from a nearby lightning strike.
