In a ladder diagram for a MEP 12, where is the positive side located?

In a ladder diagram for a MEP (Modular Electric Panel), the positive side is conventionally positioned at the top of the diagram. This layout follows the typical representation used in ladder logic, where the flow of electricity is visually depicted from the top to the bottom. The topmost representation symbolizes the supply or positive voltage side, while the lower parts often indicate the load or device connections, which can be thought of as the return path for the current. By adhering to this standard, it provides clarity and consistency for those interpreting the diagram, ensuring they can easily understand the flow of current through the circuit components.
