    Hello, I enjoy reading the Code Questions of the Day.

    I understand the NEC is finally addressing reconditioned equipment. Here is my question. Is a panel board permitted to be reconditioned? I'm getting mixed responses about this issue. Follow up question, does the NEC prohibit used equipment? Thanks for any insight you can offer.
