Tom:
Are you saying that one leg of a 240 volt circuit is 'tapped' and using the neutral of another circuit??
With all due respect to Creighton, you didn't state coming from multiple panels (sources) distinctly.
Is this a control circuit (120 volt) for a motor/machine??
Good practice would be 2 hots for 240 v; 1 hot-1 neut for 120 plus grounds as required.
As to an NEC Article?? I'll have to look tommorow; or bring this up at the Assoc. meeting Wed Nite.
John
PS: Almost forgot...I have labels stating "More then one source of power within this enclosure/equipment/cabinet"
