How is CSST bonded?

The bonding conductor must be attached to the CSST gas piping system downstream of the point of delivery (either the natural gas meter or the LP 2nd stage regulator). The bonding clamp can be located at any location within the piping system. In general, the shortest bonding conductor will be the most effective.

Do you have to bond black CSST?

CSST needs to be bonded. 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. If CSST is damaged, it can leak gas and cause an explosion and/or a fire.

How do you know if CSST is bonded?

CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home. The most common issue that home inspectors find is the CSST system is not being properly bonded. You can see that the bonding clamp is over the yellow sheathing which will not enable a proper bond.

Where do you bond the gas pipe?

Corrugated stainless steel tubing (CSST) gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall be not smaller than 6 AWG copper wire or equivalent.

What is bonding vs grounding?

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.

Should my gas meter be grounded?

Grounding and Bonding is one of the more involved sections of the electrical code. Things like gas piping don’t get “grounded” they get “bonded.” The meter itself isn’t required to be grounded or bonded.

Should gas lines 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 run flex gas line inside house?

In short, flexible gas lines are perfectly safe as long as they’re properly installed. If this happens, the electricity from the lightning can arc, puncture a hole in the line, ignite the gas inside, and cause a fire.

Why is bonding of gas piping required?

The purpose of bonding interior metal piping to the building grounding system is to provide a safe electrical path to ground should the metal piping become electrically energized. This safety requirement is intended to protect the system user from shock and the gas piping system from damage.

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.
