I have a question about bonding a metal gas piping system to a metal water piping system. I am using the 2014 NEC, section 250.104(B). - I have been under the assumption that gas piping in a home could be bonded to any point to a metal water piping system. However, after looking further at 250.104(B) I am really questioning my thinking on this. - I understand the gas piping system needs to be bonded to one of the items listed as (1), (2), (3), (4), and (5) of 250.104(B). I did look at the reading in the handbook that says the use of an additional bonding jumper is not always required for gas piping.... I also looked at 250.52(A)(1)... Honestly, I am having a hard time framing my question without writing an entire book. To the point: Is it acceptable to bond a metal gas pipe at any point to a metal water piping system, or does the gas piping system have to be bonded to a point within the first five feet of the point of entrance of the water system. - If I remember correctly, some time ago, I performed an electrical panel change and I bonded the gas piping system to a point on the water piping system that was more than five feet away from where the water piping system entered the structure. Thanks in advance for your answers!
On another note: I no longer see the stipulation, or "with five feet" rule in 250.52(A)(1) (2008 NEC) (Our jurisdiction never adopted the 2011 NEC) If we use an underground water pipe as an electrode do we still have to make our connections withing the first five feet?...
