How To Bond Csst Gas Line

He said to Bond the gas line since there was csst connecting the gas line to the heater. Cases have been reported involving CSST systems damaged during lighting storms due to inadequate electrical bonding to ground. I hope to find a knowledgeable contractor to do this work but I want to understand what needs to be done. I know the gas line to a gas furnace or gas stove that is properly grounded is considered bonded. ICC Evaluation Service PMG Listing Directory. Surrounding circuits: Plan your bonding conductor relative to the rating of the circuit nearby, as this is the source of the potential electrical arc. Trust me I know about and understand all about grounding and bonding of a service. CSST offers many benefits over old tubing, and it is pretty easy to install new parts as you apply your bonding. Electrician clamped the wire from the gas line to the main ground wire. The legislation requiring this disclaimer passed a couple of years ago when the state legislature decided that un-bonded CSST provided a substantial fire hazard from lightening strikes. Let's start with bonding piping systems. 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 clamp used must be listed for the location and type of mechanical attachment. 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 A Gas Line Casino

I can bond it at the panel since it is right next to my water heater. My questions are: -. Inspection: Examine all equipment carefully before bonding. One or more grounding electrodes... the gas piping can be bonded directly to any of the grounding electrodes without making the gas piping another grounding electrode. When our propane system was converted to natural gas the contractor used a combination of existing iron pipe and yellow CSST pipe. The Electric Connection offers grounding and bonding for natural gas lines for residential and commercial properties. If it's a good... "good"... ground path it may survive a lightning strike... "may". "It is not required. Only the electrical distribution system is grounded. Similar Threads: 01-31-2019, 07:42 PM #2. This can create two hazards: Any person or animal in the area could suffer a high-voltage electric shock. I am not arguing the wording and your post but In reality the words do not change whats installed..... A pig in a dress is still a pig............? In this article, we're going to examine how exactly you can bond a gas pipe. The intent of the code is to provide a Grounding electrode to communicate/dissipate to the ground.

1 for ground fault protection. They are connecting it ahead of the meter. Before turning on the gas: Ensure the bond has been fully completed before turning the gas back on. System is required by local codes, a bonding clamp must be attached to either the brass TracPipe? I have had spirited conversations with some people about this. From the 2017 NEC: - 250. 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. Does anything need to be done to insure that the three runs of CSST meeting at the iron manifold are electrically connected? Lightning is a highly destructive force. Black pipe will have greater resistance than copper, so there is a possibility of a difference in potential voltage at various points along the piping, but in a residence it should not be significant. As far as the connection itself, as inadequate as it might be, a loose connection causes arcing and I am quite sure that lightening will not care. The resulting electrical surge could create small holes in the piping, which can cause a gas leak that is not easy to notice. 122, where we size equipment grounding conductors in accordance with the OC protection of the circuit that we want to trip in the event of a fault.

How To Connect A Gas Line

A gas line bonded supply would have just that if there were neutral supply issues as the current would use the gas line as a conductor to find a return path to the transformer. This has resulted in the dangerous release of gas. Because CSST gas pipes can bond inside and outside your home, this gives you a lot of breathing space on where you can put this accessibility point. 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.

How To Bond A Gas Line Of Credit

Again, feeling some resistance is expected. Expert tip: Plug or tape tubing ends to prevent any dirt, dust, or debris from entering during the entire bonding process. 02-14-2019, 09:51 PM #18. If lightning strikes an ungrounded natural gas pipe, the energy from the lightning bolt could cause the gas to ignite and explode.

Why is this important? Pipe straps, bands, or hangers for securing pipes. This keeps complications to a minimum and protects the pipeline's structural integrity. In simple terms, it connects metal parts and piping to a grounded conductor. Bonding gas equipment normally relies on smaller conductors used for motors associated with residential gas equipment. Piping System Considerations. I suppose a really high voltage could breach the PVC wrap, but it would prevent the gas pipe from being an effective grounding electrode. Gas pipes should have a bend radius of 8" or more, which helps reduce potential arcs from jumping to other conductive surfaces, improving the bond's effectiveness. 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. The corrugated stainless steel tubing portion of the gaspiping system shall not be used as the point of attachment of the bonding clampunder any circumstances. What's more, bond it with a conductor that is exempt from the rules about protection from damage. I haven't asked yet. 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.

A note on regulations. 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. 104(B) Other Metal Piping. Therefore, the jumper above the water heater is required. Properly bonding and grounding of a Corrugated Stainless Steel Tubing (CSST) system may reduce the risk of damage and fire from a lightning strike. The manifold also feeds the furnace with iron pipe and the fire place with another section of CSST pipe. Occam's eraser: The philosophical principle that even the simplest solution is bound to have something wrong with it. The bonding of natural gas pipes involves bonding the service equipment enclosure, which is located above ground, to the grounded electrical service system. The instances we've all seen of CSST perforation and the resulting fires occur from the high current imposed by a lightening strike energizing and damaging the CSST itself as it arcs off of it to adjacent metal. Not jumping to and from the CSST. The points of attachment of the bonding jumper(s) shall be accessible. You should always consult an expert's second opinion and ensure bonds follow accordance with the law. It can then jump sporadically jump as an arc and cause a fire. Sorry, I apparently misunderstood your question.
