What does it mean to have gas line bonded?
electrical potential
When it comes to gas piping, not so much. Specifically, electrical potential. In fact, that applies to all metal piping systems inside a home. To make it really simple, when metal that can carry electricity (but shouldn’t) gets connected together to eliminate potential, we call it bonding.
Where do I bond gas line CSST?
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.
Does gas pipe need to be bonded?
3.14(a) in NFPA 54 requires each aboveground portion of a gas piping system upstream from the equipment shutoff valve to be electrically continuous and bonded to any grounding electrode. Sec. 250-104(b) of the National Electrical Code (NEC) agrees with this mandate.
What are the bonding requirements for gas piping?
BC Electrical Code rule 10-406 defines the current bonding requirements. 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.
Why is metal piping bonded to the grounding system?
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.
Can a gas line be bonded to a grounded conductor?
ANSWER: Yes, I said metal gas piping should be bonded to the supply system grounded conductor. The supply system grounded conductor is the conductor that is intentionally grounded.
What are the requirements for gas piping in Canada?
CSA B149.1-15 Natural Gas and Propane Installation Code (B149.1) clause 4.7.3 requires that interior metal gas piping or tubing that may become energized shall be made electrically continuous and shall be bonded in accordance with Canadian Electrical Code, Part I. requirements (BC Electrical Code).
What kind of bonding is required for gas piping?
This section’s requirements are explicit in that not only interior gas piping, but also that each portion of an aboveground gas piping system shall be bonded to the grounding electrode system. This includes exterior as well as interior metal gas piping.
Can a gas piping be bonded to an electrical electrode?
The option of bonding to any installed electrode is contingent on the additional electrodes bonded to the electrical being service grounding electrode system or where provided, lightning protection grounding electrode system . Where a lightning protection system is installed the bonding of gas piping must be in accordance with NFPA 780.
Is the bonding and grounding of gas piping controversial?
Judging by the responses to NECA’s online “Code Question of the Day (CQD),” gas piping and its use in bonding and grounding sure generated controversy and explosive comentary. The following questions and answers should clarify what many readers are asking.
What do you need to know about gas piping?
All gas piping systems are required to be bonded according to the National Electrical Code (NEC), National Fire Protection Association (NFPA) 70. See figure 1 and/or 2 below. Bond wire must be #6 or equivalent. 9. Call the Building Safety Department at 589-4150 with any questions, when in doubt, or to set up an inspection. DON’T 1.
