    CQD 9/30/22

    Dear CQD, thanks for this wonderful learning experience and the free service the CQD provides. Can you explain the intent of Section 312.2 of the 2020 NEC®? More specifically explanations of the methods for meeting the 1/4inch of airspace requirements, and the use of fittings.

    Thank You,

    Willy Culley II
