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

In a MEP 12 ladder diagram, the positive side is conventionally positioned at the top of the diagram. This aligns with standard electrical schematics where the power supply is represented at the top and the ground or negative side at the bottom. This layout helps in visualizing the flow of electricity in a logical manner, as current typically flows from the positive side downward to the negative side through the components connected in the circuit. Understanding this organization is crucial for reading and interpreting ladder diagrams effectively, ensuring clarity in understanding the electrical circuitry being depicted.
