Bonding the CSST means that you’re making sure it’s at the same electrical potential as everything else. If CSST is installed without being properly bonded to current standards, you have an increased risk for damage to the material from a nearby lightning strike.
How do you bond CSST?
Quote from the video:
Quote from Youtube video: Metal. Then run the minimum six gauge copper wire through the bonding clamp. This wire is then attached to the homes grounding network via the grounding bus bar in the panel.
What is direct bonding of CSST?
A direct bond consists of a listed grounding clamp and separate conductor run from the gas piping to the grounding electrode system. The 2018 NFGC requires a direct bond for Corrugated Stainless Steel Tubing (CSST) gas piping that does not have a listed arc resistant jacket or coating.
Does Counter Strike need to be bonded?
Counterstrike® must be bonded in accordance with the National Electrical Code NFPA 70 Article 250.104 in the same manner as the minimum requirements for rigid metal piping. However, installers must always adhere to any local code requirements that may conflict with these instructions.
How tight can you bend CSST?
Bends will reduce the gas flow and very sharp bends could weaken the tubing. The recommended minimum bend radius is 3 inches for N4 inch and smaller diameter CSST and is 5 inches for CSST from 1 to 1 1/2 inches diameter. The absolute minimum bend radiuses are I and 3 inches respectively.
Does all CSST require bonding?
All new CSST systems must be bonded regardless of whether the systems include only CSST or include other piping materials (steel pipe or copper pipe/tubing) in combination with CSST. Existing non-CSST piping systems must be bonded when CSST is added to the system regardless of the length of CSST added.
What is difference between grounding and bonding?
Bonding is the connection of non-current-carrying conductive elements like enclosures and structures. Grounding is the attachment of bonded systems to the earth. Both are necessary to safeguard people and property from electric hazards.
Does CSST gas pipe need to be grounded?
Electrical Bonding Must Be Present In Homes With Csst Gas Lines — to Reduce The Risk Of Fire Or Explosion Resulting From Damaged Gas Lines In The Event Of A Lightning-strike. CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home.
Does my gas pipe need bonding?
There is no requirement to main bond an incoming service where the incoming service pipe and the pipework within the installation are both of plastic. Because it’s not an extraneous-conductive-part. It’s plastic.
Should gas piping be grounded?
CSST Gas Lines Must Be Grounded
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. If you have CSST in your home and gas supply line work was done there since 1990, you need to be sure it is safe.
Can you bend CSST 90 degrees?
A rigid pipe install requires careful measurement, cutting and assembly of a series of 90-degree elbow fittings. CSST, however, can be quickly bent and routed where needed.
Can you bond CSST to water pipe?
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.
Where do I bond the gas pipe?
Section 250-104(b) does require that metal gas piping should be bonded to the grounding electrode system. This can be done by terminating at the neutral bar, or any of the electrodes in the grounding electrode system.
Is earth bonding still required?
Supplementary equipotential bonding (between waste pipes, metallic service pipes and earth connections of bathroom equipment) is no longer required if, and only if, the main bonding between metal service pipes can be proved to be continuous.
Is gas bonding a legal requirement?
As of 2008, earth bonding is a legal requirement for any electrical installations in rooms that contain a shower or bath. The term ‘earth bonding’ refers to the use of a thick green and yellow copper cable to connect your gas meter or consumer unit to incoming supplies such as your gas pipe.
Does earth bonding have to be visible?
A recent electrical inspection has thrown up 2 issues in the ‘safe but not great category’: The earth bond (though present and satisfactory) to the kitchen sink pipes is not visible.

How do you test for earth bonding?
The earth bond test passes a test current along the earth cable from the pin of the plug to the bodywork of the appliance. The appliance tester then measures the resistance of that connection. If the connection is rusty, non-existent or corroded then the earth resistance reading will increase.
What size should earth bonding be?
2. The main protective bonding conductors shall have a cross-sectional area of not less than half that required for the earthing conductor and not less than 6mm².
Can you link gas and water bonding?
Depending on the route of the pipes, it would be permissible to bond the water pipe (at point of entry) as normal and then connect the gas pipe (at point of entry) to the water pipe at a convenient location; i.e. to use the water pipe as the bonding conductor for the gas.
Is supplementary bonding required?
You may need supplementary bonding for rooms containing a bath or shower, except where all circuits in the room are RCD protected and the main bonding is up to the required standard.
Where should water bonding be?
Main Bonding (Earthing)
Connections are made on the metal pipes near the point at which they enter your home, i.e. The Main Bonding for the water is normally connected within 600mm of your Water Stop Tap. Main Bonding is there to protect you.
