quote" Mike, while I'm sure everyone agrees that is a good practice, is it actually stated in the code as a requirement? Don't get me wrong, I always put them on opp legs, but what would be the violation if say it was 2 dedicated ckts with the total load on all conductors, neutral included, within their ampacity?"
BigB you are correct here there would not be one in that situation. However then it would not actually be a multiwire branch circuit, but two circuits sharing a grounded conductor. NEC 100-1
