Bonding water & gas pipe with same wire

[Short.Circuit]

I do this all the time & no insp. has ever turned it down. I bond the gas pipe & the metal water pipe with the same wire. Is this up to code?? I'm just curious.
Thanks in advance!

If the wire is sized correctly it is not a problem. (It may need to be continuos depending on the set up).

Maybe this will help. Check out 250.52 (B) and FPN.

I wonder if he needs to bond to the gas pipe at all. If the gas pipe is not likely to become energized then I would say no.

If it connects a stove, fireplace w/ blower, tankless WH, or other electric appliance, I consider the size of the circuit feeding that appliance the largest to likely energize the gas line, and size the grounding conductor based on that. Unless their is a larger circuit that is in proximity crossing the gas line that could come in contact with the gas line assuming the worst; so if it is crossed by 4/0SER, I would consider the 200A service the largest likely to energize. That may be overkill, but I've never had it explained so that's how I work it.

Aren't you doing more than "to code" by opting to bond both?

Hit the duct trunk too while your at it, I did in my house.

In Oregon, you have to bond the gas pipe. Seems silly sometimes... but we do it. Thx for all the help.

I let the branch circuit EGC take care of it.

250.104(B) Other Metal Piping. Where 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 the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122, using the rating of the circuit that is likely to energize the piping system(s). The equipment grounding conductor for the circuit that is likely to energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.

I agree, according to the NEC that's all that is required. You certainly can exceed the requirements if you prefer.

Thats all I do.

According to who? Whom?

Is this something that is actually required or is just one of those things that everybody does?

 

[Minuteman]

If the gas service is located near the electrical service then I bond it. Also, if there is CSST installed, then I bond the gas service.

 

[electricmanscott]

If the gas service is located near the electrical service then I bond it.

So if it's not close by it doesn't matter?

I know in my area some inspectors try to make electricians bond to gas pipes with a solid copper 6 AWG to the main service disconnect, even if the gas pipe is not likely to become energized. I argue with them every time and they can never give me a reason why they want it done.
It seems to me if you bond to a gas pipe that is not likely to become energized, to the main service disconnect, you could be causing more problems. If POCO ever lost the neutral to the building the gas pipe could now become be energized.

The egc is not suitable for a gas pipe bond. A gas pipe bond needs to be a minimum of #6 copper but most inspectors make you use the same size as the gec. You must not have done a new service lately

You must not have read 250.104(B) lately. Check the second-to-last sentence.

edit to add: Check post #8. Chris already posted it.

This is incorrect but I am afraid that comments may be made based on CSST piping. Some CSST piping needs to be bonding with a #6 per manufacturers specs while other CSST, such as , counterstrike by Omegaflex does not need to be bonding with anything other than the EGC

One thing I've learned in all my years of internet geekery is that if you are going to get uppity you better know what you are talking about and more importantly be correct.

I just figure, that if it's in close proximity to the service, than it ought to be the same potential. No one has ever told me what "likely to be energized" means.
