Typically, PDB’s facilitate getting power from the Main (high ampacity) to the Load (low ampacity), while conforming to Codes and specs.
The “Primary” is the input side of the PDB and accepts large wires from the main switch.
The “Secondary” is the output side and can usually accommodate a lot of smaller wires that continue on to the loads.
