Many Thanks to all hands. A special thank you to Joe Tedesco for the specific section reference. Every time I run into this practice it is causing some sort of problem. When I was assisting with housing inspections it repeatedly caused elevated voltage drop on the ungrounded current carrying conductor / Equipment Grounding Conductor circuit. I have encountered it so many times that I began to think that it had to have been code compliant at some point in time.

On the sign issue are you saying that splices made by twisting the wires alone are code compliant in neon sign work? That seems so strange!
