There are some local amendments but they are usually prohibitive or they require extra. I believe Chicago required pipe for a long time, I have heard of a couple in regards to grounding but none that disregard a fundamental principle they adopted when they wrote the first book. Why would they have all these plugs if it didn't matter?
The IRC or whatever it is prohibits even multiples of 240 on the same circuit in excess of the NEC and with good reason obviously, just to prevent some dope from causing a situation like this. They must figure that isolating it to a single outlet reduces the chance for error. Keeps someone from overloading an underwired circuit in relation to the breaker, a welder outlet may come to mind.
There is a safe way to do it but its obvious from this thread that there is a lack of understanding of some general principles, cant insure every installer fully understands complete circuit design so the simple way around it is to rule it out where the maintenance is not under professional supervision.
I am skeptical about a lot of guys that do this work, lots of plant maintenance people learn hand to mouth.
We saw one here where the "electrician" from Dads work wired a 7 1/2 hp comp with a 12 cable. Probably did this at work on 480 3 ph, never been tested or educated in basic install.
I went to a call a while back, the preacher had his bud the maintenance guy did electrical at the church come and do a service install. The inspector must have got tired of looking at it and passed it anyway, when they turned it on it tripped a breaker, dipstick couldn't even run a foot of wire to an outlet without shorting it.
I had a chance to look at a panel a while back and I can count at least 5 electricians that work on it. The last master that went over it is not a fussy type but a brilliant guy, he fixed up some simple stuff but it fooled the maint guys that called me. I recognize a couple guys before me, 2 of them left their 'fingerprints" as I had seen it before and one does dumb stuff because he really knows more about it than most people including the masters before him and the code book.
