Let's start with bonding piping systems. Last time I checked the bonding of CSST was a manufacturer's requirement and not an NEC code issue. This takes place where the gas lines enter the home or building. I see no attempt to bond/ground the gas piping. Your safety cannot be compromised or ignored. Deburring blade or utility knife. Standard CSST installed insideor attached to a building or structure shall be electrically continuous anddirect-bonded to the electrical ground system of the premises in which it isinstalled. Old time lightening rods on barns are a perfect example of this. Ensure all surfaces, including the pipe's interior and exterior, are clean and free of chemical agents. Bond wire for gas line. The bonding conductor(s) or jumper(s) shall be sized in accordance with 250. The gas piping system shall be considered to be direct-bonded wheninstalled in accordance with the following: The bonding conductor is permanently and directly connectedto the electrical service equipment enclosure, the grounded conductor at theelectrical service, the grounding electrode conductor, or to one or more of thegrounding electrodes used. Ensure the bond is free from dirt, debris, or harsh chemicals. The results of an improper gas pipe can be costly and, in some cases, fatal.
I would have thought that the PVC wrap would also essentially isolate the pipe electrically from the soil. All applicable CSST bonding requirements must be met unless the piping material is certified for lightning strike protection. Bonding electrode conductor sizing shall be in accordance with NFPA 70 Article 250. Bob, I do not believe that bonding to the CSST will actually allow it to be a part of the ground path, any more than attaching to hard pipe or a fitting. If it's a good... "good"... ground path it may survive a lightning strike... "may". The following items are typically used as electrodes: - Plates. 06-24-2019, 07:35 PM #27. 03-03-2019, 06:51 PM #21. I have had spirited conversations with some people about this. Trust HELP for Gas Line Bonding in Greater Cincinnati & Northern Kentucky. Knowing how and when to report a gas leak to emergency services and how to avoid leaks in the first place is vital to the safety of your home and the people living in it. The equipment grounding conductor for the circuit that is likely to energize the piping shall be permitted to serve as the bonding means. CSST Gas Line Bonding - Electrician Services Offered by Daniel Electric. Pipe straps, bands, or hangers for securing pipes. Even a nearby lightning strike that does not strike a structure directly can cause systems in the structure to become electrically energized.
In Theory there is NO difference in the way they are bonding the gas line then one would utilize the metallic incoming water line.. Trust me I know about and understand all about grounding and bonding of a service. Expert tip: If applying the clamp to the pipe's surface, ensure it has been sanded down to bond to bare metal. Electrician clamped the wire from the gas line to the main ground wire. Can the system be bonded to the electrical panel from the iron pipe serving the water heater? If ignited, this could cause a fire or small explosion. I don't know about other parts of the country but where I worked the gas utility would have a fit if they found a connection between the incoming supply (pre-meter) gas line and the electrical panel. How to bond gas line. A different discussion). All answers based on unamended National Electrical codes.
Inspection: Examine all equipment carefully before bonding. If lightning strikes an ungrounded natural gas pipe, the energy from the lightning bolt could cause the gas to ignite and explode. Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling. ICC Evaluation Service PMG Listing Directory. What is gas line bonding. It looks like there may be a dielectric union on the house side of the gas meter but I have not verified that the house is isolated electrically from the meter. Local requirements vary.
There is other csst in the house so I want to get it done. Surrounding circuits: Plan your bonding conductor relative to the rating of the circuit nearby, as this is the source of the potential electrical arc. The conductor can be installed indoors or outdoors. 02-13-2019, 11:57 AM #17. However, as discussed, the code says that it can be bonded with the heater grounding conductor.
Hopefully as plastic pipe starts replacing metallic pipe even in older residences all the "I've got a better way" crap local jurisdictions come up with regarding this stuff will start to go away. If installed IN, or ATTACHED TO, a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to any of the following: (1) Equipment grounding conductor for the circuit that is likely to energize the piping system. The meter is on the opposite side of house from the electrical entrance and the electrical panel. But if in doubt, remember: - A tight seal is essential for establishing a proper gas flow. 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. Whether it's shielding you from lightning strikes, or an electrical build-up that arcs to other metal surfaces, a proper bond is an ultimate defense. All of the more current buried pipe that is installed by the utility company is plastic. How to Bond CSST Gas Line. It does not constitute professional advice. I am guessing here, but my local AHJs might be figuring that CSST is going to be installed at some time in the future and they want to make sure that it is bonded, even if an adventurous homeowner does it. See 2018 International Fuel Gas Code. Hopefully, Jerry Peck will chime in soon to tell me why I am wrong and what I missed. All of my water lines are bonded but the gas is not. The information I find is this.
Bonding and grounding reduces the risk of arcing and other related damage. The bonding will help achieve an equi-potential state between the CSST and other similarly bonded metallic systems (such as the water piping, structural steel, electrical raceways and coax cable). In reality the Grounding electrode is basically for surges and lightning strikes. Nothing will "eliminate" the risk with CSST, reducing the risk is all which can be hoped for.
Next, grab your bonding conductor. Gas line bonding is the process of linking steel or copper gas line piping to your home's ground wire through a separate bonding wire. All of our electricians are licensed and insured, so you can have confidence that you're receiving services performed by experts. Tying the hot and cold together at the water heater isn't a bad idea but the connection is often times made by a tub/shower valve. In a ground fault of the circuit, the current is looking to go back to the source not earth.
