Iwire...I am truly sorry- I did not mean to insult you, or anyone else!!
What I did mean was to contrast the hard-working guy, who learned the trade 100% in the field, doing the same sorts of jobs for the same employer, and by virtue of his time in trade calls himself a 'journeyman,'....and someone with a braod range of experience, backed by a systematic education in all facets of the trade.
I was also referring to the idea that 'journeymen,' by virtue of their training and experience, are paid for their knowledge and judgement. Contrast this with the attitudes of some, who consider even the most qualified tradesmen to be little more than apes with tool belts!
Disagreements? You bet- especially when a question takes us off the beaten track. And, yes, it is possible that actual experience at an installation will confirm some of these design calls...and discredit others!
Again....I didn't mean to insult you, or anyone else.

OK points noted.
Now.... Here's where I think I have figured out where I differ from everyone else on this topic... "30 amp general purpose circuit" is not in my vocabulary. In my mind, general purpose circuits are 15-20, depending on what they are intended for. Especially, when I know what they are intended for. And yes, I do ask what they are intended for. 30A circuits, are individual branch circuits - in my mind, something I do not think will change for me.... And maybe thats a design issue.... My apologies.
Now a question, and I am not asking this to be cheeky.... For those of you who do install 30 amp general purpose circuits, how many outlets do you generally put on one? Would they to be counted as 180VA per strap?

Thanks Reno. Mark? (It is Mark right? sorry I stink with names even though I can remember code sections I don't think your question is bad at all. I can not think of a time where I have installed 30 amp GP circuits. But they are not prohibited by the NEC. I have seen 50 amp welder outlets installed with many outlets on one breaker, there is one welding machine rolled around to different locations.

by 630, they use #10 conductors to wire a 50A receptacle for it. The new owner has a 40 Amp Kiln that they use for firing pottery. New owner is delighted to find the 50A recptacle (and circuit breaker) already installed. Interesting point, there would be no outward signs to a layman that they are doing anything wrong. Bob

I would have a lot more trouble with a 50a receptacle on 10ga wire than ten 30a receptacles. To start with I would see no relief from 240.4(D) if this was a receptacle.

Greg
"Unless specifically permitted in 240.4(E) through (G)"
'G' would allow the 10s on a 50 suppling 50 amp receptacles.
