Hello, I'm wondering if someone here might be able to give me some pointers on industry standards for control panel wiring. I'm looking for some of the basics. I have helped to wire a couple of panels for some inhouse built machines in the past, but we didn't follow any standards. 1. We typical use non-fused type AB 194R rotary disconnects on our machines. The line voltage coming into the control panel is 120VAC 1phase. Is it common practice to wire the hot and neutral lines thru the disconnect or just the hot line? I have seen it done both ways. 2. Is there a standard for wire numbering convention? For instance, how should the numbering label sequence for the control wiring be handled. How do you know how to label wires and when to change the number? Any info. would be greatly appreciated. Thanks
