    I don't know what CSST instructions say but many seem to think it must go to the electric panel and not to the ISBT though.
    I live for today, I'm just a day behind.

    Of the few I have installed, most got split-bolted to the GEC in the crawl space.

    What few? CSST bonding or the ISBT?

    CSST bonding; I don't know what ISBT is.

    I think it's short for:

    We have talked about this csst going to the intersystem bonding but at the big meetings it was stated that the intersystem bonding unit was not listed for bonding of csst. Local inspectors still allow it at times however most units have only 3 ports for other utilities so if you use one for the intersystem then you only have 2 left. Can one argue that the csst is another system???

    Consist of a set of terminals with the capacity for connection
    of not less than three intersystem bonding conductors
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    Here.
    https://cdn-web.iccsafe.org/wp-conte...Notes_CSST.pdf

    "The permanent bonding of corrugated stainless steel tubing (CSST) piping system directly to the grounding electrode system of the structure in which the CSST is installed will lower the voltage build-up on the CSST caused by unintentional energizing from outside sources such as power surges and lightning strikes"


    Must connect to the GEC not to the EGC. Minimum wire size #6 cu.

    Is there anywhere in the gas code that states the connection must be continuous? I don't think so so if the equipment grounding conductor to the sub panel is a #6 then the csst bonding should be allowed to connect to that panel.

    It says connect to the grounding electrode system.
