This AutoCAD DWG file includes a complete Single Line Diagram (SLD) of a Distribution Board, showing circuit breakers, wiring connections, and load distribution for lighting, power, and mechanical systems. Does anyone have examples of how they are drawing M12 distribution boxes for field attachables and IO? For example, I am using an Allen-Bradley 898D-P58DT-B5 for connecting in several proximity switches. I'll be using it with Y-splitters to get two switches into each port on this 8 port box.
