    First if this is a factory assembled control panel, the NEC does not even apply to the internal wiring.

    Just like every time the code requires something in a specific room or area, we have battles over those areas...this will require a definition in the 2017 or 2020 code.

    There is an ongoing process to bring the two codes closer together. The changes in the ampacity tables for the 2011 NEC was part of that process.

    Given what I have read about the issue, I think the wall thickness is the main factor. The damage occurred when lighting induced currents on the CSST jumped from the CSST to another conductive...

    That is true, but you are talking about an actual strike. The damage to the CSST has been from remote strikes. If there is a direct strike, it won't make a lot of difference what your gas pipe is...

    That all sounds good, but it still seems to me that with the same amount of energy, the damage would always be worse for the CSST.

    The amount of energy required to punch a hole in the material should be more related to the thickness of the material than anything else...I guess I am really thinking more of thermal mass.

    Charlie,
    If you have some time you could read Validation of Installation Methods for CSST Gas Piping to Mitigate Indirect Lightning Related Damage
    The document is over 200 pages.

    With the threads tight enough to prevent leakage, I still think there would be a lot more mass at the threaded connection than you would have in the wall of the CSST.

    Just looking at the wall thickness of the two products, I can't see how it would be even physically possible that lighting could damage black pipe easier than the CSST.

    I have been taught that you never re-torque a wire connector where the bolt or screw that you are re-torquing is directly applying pressure to the conductor.
