2.7 IEC PCB Wiring
Now we'll wire the IEC PCB, which will make the remaining wiring from the Rocker Switch to
the Mains transformer much easier to follow and to implement.
120V and 240V Operation
Cut the four wires (White, White-Grey, Black, and Black-Grey) coming out of the Mains
Primary to 30 cm. Strip and tin the ends. (You can add some heat shrink if you like.)
Connect these four Primary wires to the IEC PCB as shown in the diagram below.
