Let me be the devils advocate...at the risk of starting a firestorm.
You have the luxury of taking a somewhat high and mighty attitude with respect to the NEC, because it is a National Standard, and of course who can argue about safety!
With plumbing, we are also concerned about the health and safety of the populace, AND we have to deal with codes that vary from state to state, and town to town, and in California can vary from building to building .
Plumbers argue about the appropriateness and interpretation of codes all the time. I have noticed plenty of articles on the internet where the "sensibility" of code sections is questioned, as is the motivation of those who write the codes. Just like it is in the plumbing codes.
Anyway, we don't want anyone hurting themselves with gas, or backflow, or carbon monoxide, or with electrons.
When obviously incorrect or unsafe information is posted in any category, we hope a moderator or another forum member will jump in on it. As for deleting posts, especially in electrical, we will leave that to the electricians and Terry. I don't know what was up in some of the threads....but for the reocord this moderator did not delete any posts, even if we would like to invite Ian to a Boston Tea Party!
