This energy is enough to damage copper and steel piping and the flexible connectors between sections of pipe. In the video below, Mike Holt Enterprises explains precisely what the terminology demands of you: Step-by-step on how to bond gas pipes: The below steps focus primarily on installing and bonding CSST (corrugated stainless steel tubing). The means for attaching the bonding conductor to the grounding electrode system must be in accordance with NFPA 70. The bonding of corrugated stainless steel tubing (CSST) piping system to the grounding electrode system of the structure in which the CSST is installed will lower the voltage build-up on the CSST caused by unintentional energizing from outside sources such as power surges and lightning strikes. This type of bonding can be done on newly built homes as well as older homes and buildings. For this reason, this appliance does not need bonding. As we all know, homeowners rarely let a lack of knowledge stop them from making modifications to their homes. The results of an improper gas pipe can be costly and, in some cases, fatal.

Bond Gas Line To Electrical Panel

CSST was first introduced to the United States in the early 1990's. That said, we recommend that you always try to take the most direct route from your gas appliance or existing pipeline to the gas meter or grounding electrode system. The bonding should be in accordance with the National Electrical Code NFPA 70. 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. Re: gas line bonding. Hopefully, Jerry Peck will chime in soon to tell me why I am wrong and what I missed. 02-13-2019, 11:57 AM #17. They are connecting it ahead of the meter. The meter is on the opposite side of house from the electrical entrance and the electrical panel. Reference Number: IB-GA 2017-04. 7 requires that interior metal gas piping systems connected to a gas-fired appliance with an electrical connection shall be made electrically continuous and bonded in accordance with CSA C22. Let's start with bonding piping systems. Columbus, Ohio, is no stranger to severe weather, including thunderstorms that produce lightning strikes. 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.

Bond Wire For Gas Line

1 for ground fault protection. Think of it this way: Interior metal water piping and underground metal water piping. 5) One ore more grounding electrodes used****. Electrician clamped the wire from the gas line to the main ground wire. Next, using a wrench, slide the nut over the bushing. Only a single point of attachment is required regardless of the length or complexity of the piping system. Concrete encased reinforcing steel.

How Much Does It Cost To Bond A Gas Line

The jumpers are usually made of thick copper wire. Does anything need to be done to insure that the three runs of CSST meeting at the iron manifold are electrically connected? Bonding electrode conductor sizing shall be in accordance with NFPA 70 Article 250. The picture I posted shows an improperly bonded CSST gas line more likely to create damage than to avert it in the case of a lightening strike. The manifold also feeds the furnace with iron pipe and the fire place with another section of CSST pipe. Local requirements vary. I have a difficult time with bonding myself. In Maryland we are required to include a statement in the report for homes that use CSST gas lines. It might just be redundant, it might be to ensure bonding without relying on a mixing valve or it might be that some plumbing fixtures are coming out with nonconductive materials. Not a position substantiated by any research I've done or the millions of installations across the country (there are no successful class action lawsuits against CSST), but it does conveniently relieve Home Inspectors in Maryland from any liability. However, now that you bring this up, some of the newer high-efficiency water heaters do use 120 volts to power the forced-draft blower.

How To Properly Bond Csst Gas Line

Place the cut end into the stripping tool, apply gentle pressure, and rotate until the blade cuts through all jacket layers. Contact us for complete details. The gas line cannot be used for the purpose of a Grounding Electrode, you must provide some other GE such as water line, UFER, plate, ring, or rod. Reduced risk of penetration of the CSST, and leakage which will follow. 3) Grounded conductor at the service**. This is in addition to the bonding required in Section 310. We always leave your home cleaner than we found it…Guaranteed! I can see the debate about the gas line being used as an electrode.

How To Bond A Gas Line Of Credit

FAC: Some gas appliances come with their own gas distribution system known as a 'flexible appliance connector. ' Create space: Regardless of vertical or horizontal piping, create as much space between the bond and other metal systems that may be under flooring or underground. 7 further provides specific requirements for corrugated stainless-steel tubing (CSST) systems. The key at that point is to keep the lightning energy already on the CSST... on the CSST. Run this through the bonding clamp. Use can use a deburring blade to soften the edges. Grounding a gas line is as simple as attaching a wire from the gas pipe to the service panel or ground rod. Original yellow jacketed TracPipe? The location of the bonding clamp on the gas piping system must be selected so as to comply with the maximum allowable conductor length. Any newly installed gas line with CSST will be bonded, but this service will increase home safety if you have an existing gas line without bonding. Trust me I know about and understand all about grounding and bonding of a service.

Do Gas Lines Need To Be Bonded

Cutting pipe to exact measurements. Can the system be bonded to the electrical panel from the iron pipe serving the water heater? Again, feeling some resistance is expected. Provincial Safety Manager, Gas.

How To Connect A Gas Line

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. Information Bulletin: Electrical bonding requirements for gas piping systems. Around here, any buried gas pipe must be factory-wrapped (I believe the yellow stuff is PVC) to prevent corrosion. This can be either solid or stranded copper or aluminum – so long as it is not smaller than or equivalent to a six AWG copper wire.

A CSST piping system is considered to be electrically continuous (using CSST and other code-approved piping materials) and only requires one clamp. This applies to both new and existing systems. Neutral) and the grounded ( Neutral) / grounding ( ground) connection is so important. Now if... that Big IF... Equipotential bonding of nonelectrical systems including gas piping systems is regulated electrical work. Deburring blade or utility knife. In a ground fault of the circuit, the current is looking to go back to the source not earth. References: Gas Safety Regulation. Expert opinion: Home inspectors can examine your gas piping system, plumbing, and gas appliances for unforeseen hazards, especially if you are in an area prone to lightning strikes. A HISTORY NOTE: Corrugated stainless steel tubing (CSST) originated in Japan as a solution to damaged gas piping caused by earthquakes.

So why are my local building departments requiring the independent bonding? I hope to find a knowledgeable contractor to do this work but I want to understand what needs to be done. I recently became aware of the need to bond a gas distribution containing yellow CSST flexible pipe. My question is this.
