Are we the point where people just need to come up with ridiculous code changes and the CMP accepts them with little or no substaniation? Really, more than 4 each counts as 1/4, this is starting to sound like a joke. :slaphead:

Yes, we are. It's a steady decline. I mean it when I say we need to go to a ten year code cycle.

The constant micro-tweaking is very annoying, more often than not unsubstantiated, and not in line with the real purpose of the NEC which is safety.
