The risk is tremendously reduced when CSST flexible gas lines are "bonded " (BONDED DEFINED: Connected with wiring to take electrical current away from CSST flexible gas lines in the event of a lightening-strike on or near the home). CSST has a proven resistance to leaks due to far fewer connections made during installation. How to tell if a gas line is bonded? The home needs to be inspected, and proper bonding (if not already present) must be installed to yellow flexible gas lines to help protect the home in the event of a lightning strike. In summary, you cannot use a metal underground gas piping system as a grounding electrode. In order to tell if a gas line is bonded, you will need to visually inspect the bonding material. If it were electrical wiring, it would be Romex®. When building officials have asked the manufacturer how much distance is required, the manufacturer has left it up to the building official. Bonding gas piping is an essential task for ensuring the safest operation of residential and commercial buildings. CSST bond wires or clamps shall ALWAYS be connected to: - Customer piping — as close to the natural gas meter as practical. Gas pipe feeds a different gas appliance in the home.

Gas Line Bonding Wire

It is engineered to significantly decrease the potential for lightning-induced damage to fuel gas piping systems IF, installed correctly. This is needed any time CSST is installed, even if it's just a small amount. THEN CALL 911 & YOUR LOCAL GAS SUPPLIER. It also adds another safety measure in case of earthquakes, which often cause fires by shaking or breaking gas line connections. A bonding wire is not designed to carry current, rather it only allows current to pass through it if electricity somehow gets into the bonded components. The manufacturers of CSST have changed their installation requirements because they've learned that the old methods weren't good enough.

Bonding Gas Line To Electrical Panel On Climate

The same is true for flexible metal piping connected to any component containing flammable liquids or gases. It's easier to install than other stuff before it, and old-school home inspectors and contractors are super-suspicious and don't trust it. We use cookies to analyze website traffic and optimize your website experience.

Bonding Gas Line To Electrical Panel Discussion

This means that if something was installed to code, it's still a code-compliant installation today, even if the codes have changed significantly. NEC also allows you to bond the piping to the equipment grounding conductor, of the circuit that is likely to energize it. Only an inspection will determine if the gas lines are safely bonded as required by today's Building, Plumbing & Electrical Codes. By bonding the lines with a copper wire, it is possible to reduce the risk of an electrical arc or spark causing damage and keep people safe. I called their building inspections department to ask about this, and was told that they only allow the installation of arc-resistant CSST products, such as FlashShield™. Propane lines coming to the home are either copper or polyethylene. Additionally, bonding clamps should be specifically designed and rated for gas service, connected securely to both the gas pipe and an approved ground source such as a cold water main or building steel frame in order to provide an adequate low impedance path. You should size the conductor just as you would size it if it were a metal water pipe isolated from earth ground because of a nonmetallic underground water supply system. The primary issue is that a lot of people don't have adequate knowledge about the importance of proper gas line bonding and why they need to get it repaired. 104, "any metal piping likely to become energized must be bonded to a grounding electrode system. " Gas Pipe Bonding Code.

We at JNR Plumbing LLC want our clients and our readers to understand the safety involved within your home. One place that isn't a proper bonding location is the intersystem bonding terminal, which can be found at the exterior of homes that have been built in accordance with the 2008 NEC or later. Grounding is done to ensure that electrical fault current can return to the utility's transformer and hopefully prevent damage to people or property. Let's take a closer look at the rules to help clarify the position of both Codes. 250-104(b) of the National Electrical Code (NEC) agrees with this mandate. CSST is typically routed beneath, through or alongside floor joists in the basement, inside interior wall cavities and on top of ceiling joists in attic spaces. Black (conductive jacketed) CSST products. When there is a reason to locate where the gas pipe is (such as digging in the area), the tracer wire can be connected to a small low voltage electrical charge. The same goes for gas lines that are not grounded. 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.

Bonding Gas Line To Electrical Panel Parallels

In more recent years, however, all manufacturers of CSST have made it a point to release technical bulletins to CSST installers ensuring they are aware that yellow CSST must be bonded and showing how it must be done. CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home. Can i simply connect it to the neutral bas lower down in the panel!? The use of nonmetallic unions or joints has the same effect. A CSST brass fitting, a steel manifold or rigid pipe component connected to a CSST fitting. 1, the NFGC states, "Gas piping other than CSST shall be considered to be bonded when it is connected to appliances that are connected to the appliance grounding conductor of the circuit supplying that appliance. " 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 size bonding clamp for bonding gas piping? Some previously installed CSST systems may not have the proper bonding for optimal safety. There are fewer leaks with CSST due to long runs and very few connections.
