Several recent threads have induced me to attempt to stir up a bit of a debate. I have hinted, perhaps even stated, my opinion from time to time. But I think this one is worth an open discussion.
QUESTION:
What aspect of the so-called ?Grandfather Rule,? or for that matter any other code article you choose to name, leads you (if by chance you have been led down this path) to conclude that,
? IF an installation is in violation of the NEC edition that is currently enforced in your area,
? THEN that installation is allowed to remain in place . . .
(NOTE: What follows is the reason for my question, so please pay attention),
? . . . IF AND ONLY IF that particular installation was allowed by the NEC edition that was in force at the time of its construction?
In other words, if you see something that violates today?s NEC, and if you are asked if it must be repaired or replaced or whatever, do you first seek to discover the date of its installation, and check to see if the NEC in force at that time would have allowed it? If so, why? What is your basis in code for looking at installation dates and old code books?
