Ok know we are on a dedicated thread.
What I would like to know is how did the interpetation go from upsizing when having long runs and voltage drop to where it has been in the last few cylces?
I read in another thread it was due to lack of enforcement. I say hogwash.
I have read the ROP from others and Dennis Alwon. I don't agree with the angle those folk are looking at. Sorry Dennis.
We have an debate going on another thread where this rule could cause unnecessary upsizing of wire due to the current and proposed language. If the intent is really all about upsize due to long distance runs then we need to keep focus on that point. This point regardless of claims of lack enforcement shall maintain of greatest importance.
The ramifications of the code as written have not yet been realized by most yet as they are un aware of the original interpetation.
The next thing we will be doing is ripping out oven circuits in homes because the owner chose to go Gas or a combo and the circuit now needs to be 20 or 30 Vs 50. How many of you code compliant people are going to break the law. Or maybe loose work to a misinformed contractor or Handyman.
If I can't use this info to make comment on the 2014 NEC at least I can try with the California Electric code wich is a later version.
I think this is a good start.
