Where does CSST need to be bonded, inside or outside of the house? The photo below shows an example of CSST bonded at the exterior of the home, with the bonding clamp connected to the CSST nut. When bonding a gas pipe to a water pipe, it is important to use bonding clamps that are specifically designed for bonding gas pipes. One aspect of maintaining a safe gas line is to ensure the line is grounded. Depending on where you're working, you should check with the AHJ for their official interpretation. The Federal Energy Regulatory Commission (FERC) governs nearly 2. This standard outlines various requirements for safely installing, operating, and maintaining gas appliances. Bonding Gas Piping is Essential (2022 Guide. That it is connected to is grounded via its electrical power connection.
The most common types are: - Yellow corrugated stainless steel tubing (CSST). To the electrical system's grounding system to ensure continuity in case the metal object were to ever become accidentally energized and/or potentially damaged due to a nearby lighting strike. Copyright © 2022 614electrician - All Rights Reserved. While a grounding wire does not always carry current, it is intended to carry electrical current at any time. In most newer homes that I inspect, I find that builders are finally getting around to bonding gas pipes and the local code enforcement officials are now requiring that the bonding exists. If it were electrical wiring, it would be Romex®. If you own a newer home or you've recently added gas lines to your home, there's a good possibility that someone used CSST. Depending upon the home, accomplishing this task can range between being very easy to nearly impossible. Bonding gas line to electrical panel discussion. It also describes a safety hazard and code changes due to the history of house fires associated with CSST when lightning strikes nearby, or worse yet, the home itself. The cost of bonding a gas line will depend on how long the bonding wire needs to be, as well as the type and size of bonding material used.
Millions of Americans rely on natural gas each day to make their lives easier and more comfortable. 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. CSST is a Gas-Distribution System. CSST Bond Wires or Clamps Shall NEVER Be Connected to: - Natural gas meters or facilities. Bonding gas lines to electrical panel. The diagram below shows an example of what this would look like when properly installed to today's standards. Bonding is provided primarily to prevent a possible electric shock to people who come in contact with the gas piping and other metal objects connected to the grounding system.
You should size the bonding jumper connecting and bonding the metal gas piping to the grounding electrode system as noted in Table 250-66 of the NEC; based on the largest ungrounded service phase conductor. The gas line adjacent to the gas meter is still often black iron but it is often either a combination of black iron and CSST inside the home. 250-104(b) of the National Electrical Code (NEC) agrees with this mandate. They may also short-circuit electronics and appliances during a surge. This means when something was installed in compliance to Building-Codes at the time of the installation — it is deemed correctly installed moving forward in time, even if Building-Codes change significantly. The video below, produced by Gastite, shows a couple of examples of properly bonded CSST. Bonding gas line to electrical panel. Unfortunately, even if most of the line does not include CSST, the line needs to be bonded using bare or insulated grounding wire. That means that the bonding conductor for CSST can be connected to the metallic water piping coming into the home, a ground rod at the exterior, or anywhere else on the service grounding electrode system. Grounding gives excess electricity a safe place to go from an appliance back to the earth. Those short lengths of tubing are not required to be bonded and grounded separately. Need Help Grounding a Gas Line?
Can i simply connect it to the neutral bas lower down in the panel!? What about the black stuff? If you want to install CSST gas line or you feel that it has not been correctly bonded, then get in touch with the Volt Doctors. My question is.. How to bond gas line in home. where should i move the existing ground wire to in the panel? A bonding device should be installed on your natural gas system in order to reduce the chances of a natural gas leak or fire. So, what's the confusion all about?
Look for flexible tubing with a yellow or black jacket that covers the ridges. Grounding 200A Main Panel with Changes to Water & Gas. Additional Information on CSST and bonding. The reason for this is that they're not comfortable with the installation instructions for the other stuff, which says "Care should be taken when installing vertical runs to maintain as much separation as reasonably possible from other electrically conductive systems in the building. A tracer wire is usually not connected directly to the meter, though it can be. Properly installed bond wires provide a low-impedance path between two pieces of metal piping, helping to ensure maximum safety when working with natural gas systems.
We use it in new installations as a complete replacement to traditional metallic piping systems or as a replacement component in older metallic systems. The main difference is a grounding wire is designed to carry current at any time necessary and carry that current into the ground. Especially if they are not protected with Bonding to ensure electrical energy is carried away from the pipe (versus carried by the pipe). However, if you are looking for one in the Raleigh area, you should consider the Volt Doctors. 3 of the Fuel Gas Code, you probably don't need any special bonding if you have black CSST.
Like all gas piping systems, CSST must be properly installed. This bond must also meet all applicable local and national code requirements. Properly bonding a gas pipe is fairly simple in most situations and should be done by a qualified electrician. When a black iron pipe is installed, every time the pipe changes direction, a joint needs to be fitted and checked for leaks. Grounding and bonding are two very different things yet, from my experience, many electricians, plumbers, and home inspectors don't know the difference between the two yet they are indeed very different. Often grounding wires are connected to a grounding rod, which is a steel rod inserted 8 feet into the ground. It can be understood that the electrical system is grounded whereas everything else is bonded to the electrical system. My panel is currently grounded to my water service, connected at the panel to the neutral feed bus (see picture). We use cookies to analyze website traffic and optimize your website experience. The first thing you need to learn about is the different gas lines. If you had gas piping system installed or modified after 1990, the chances that CSST was installed is very high. Home and building owners may not always know what is best for them. In the 2000s, manufacturers started manufacturing a different type of CSST with a black exterior sheathing (see image below) which has different electrical and chemical properties.
Grounding provides safety in case of a fault in a structure's branch circuit wiring that feeds lighting, receptacles, and appliances. The only problem we have with this concept and method of sizing is which protective device should you use: the service device, feeder device, or branch-circuit device? What defines the grounding electrode system? There is no requirement to maintain separation from other electrically conductive systems when routing FlashShield™". This is needed any time CSST is installed, even if it's just a small amount. There is a difference between CSST Gas Lines and the similar looking yellow Flexible Appliance Connectors (to be known here out as "FAC"). BUT that does not mean they are safe. However, some disagree. Yellow CSST is manufactured under various brand names including GasTite®, TrakPipe®, and Diamondback®. How else to Identify FAC: - FAC does not require bonding. Building officials aren't in the business of testing manufacturers products for safety; that's supposed to be the manufacturer's job.
The process also prevents sparking by giving electricity a safe place to go and preventing build-ups or arcs that could potentially damage gas lines. There is a lot of confusion in the home inspection and real estate industries about gas pipe bonding. 1 of the NFGC, the bonding jumper must be more than 6 AWG and be a copper wire or equivalent. Although these companies safely and efficiently provide natural gas to homes and businesses all over the country, there are some rules that need to be followed to prevent unnecessary risks and protect people from dangerous situations. That version of the NEC was the first to require an intersystem bonding terminal for low-voltage communication equipment such as television cables, satellites, and phones. We also provide a free estimate and consultation services to all our clients. CSST is flexible, making it better across long runs, and offers good damage protection during an earthquake. Other metal piping: NEC Sec. This sizing prevents the grounding wire from overloading, causing damage to the ground wire or the line it is protecting. Not only does the newest version of the code allow CSST to be bonded anywhere, but CSST manufacturers also allow CSST to be bonded anywhere.
