    Thank you Dennis

    Pulling 14/2 through 3/8 flex isn’t fun, but I’ve done it once before

    BTW, will 14/2 even go inside 3/8" flex. We usually use 1/2" carflex and have never been turned down

    The other cabinet I need to get to is inaccessible via the basement , so I’m planning on running 3/8” flex up through lower cabinet and across cabinetry above microwave (to get to other cabinets)

    Per 334.15, flex should be sufficient for protection from physical damage. But getting conflicting answers.

    Thoughts?

    Are we talking 120v lighting or low-voltage?

    What are you considering putting in the 3/8"?
