    Show me where I made a mistake via the NEC, not some document that is not the NEC.

  • Mike, I would encourage you to place a date on you chart documents that does not change whenever it is opened, saved, printed, etc. That way, one can quickly determine if one copy or print is later than another one. Just good practice. you are doing a great service to this industry. Keep it up.
