    Re: CQD answer published Wednesday, July 19, 2017 - Torqueing Terminations

    As published:

    “ It might be good to use those values in the absence of specific manufacturer's instructions but it is specifically required.”

    Or, is this correct?

    “. It might be good to use those values in the absence of specific manufacturer's instructions but it is NOT specifically required.”

    Thanks for a valuable service.

    Cordially, William H. (Bill) Hudson, CBO, MCP
