I did this on purpose so that you will automatically recognize the AC lines from the DC lines. The AC lines are thicker and are distributed using UK2.5 terminal blocks (or Dinkle DK4N termainal blocks). The DC lines are thin and use WAGO nuts for distrubution blocks. -Since the Raspberry Pi is a 3.3V logic device, I use [3.6V Zener Diodes](https://www.amazon.com/Chanzon-34-Values-Zener-Assorted/dp/B07BTWBXJ3) for over voltage protection on the Raspberry Pi's GPIO lines when using a 5VDC power supply for the 4-channel relay module to activate the relay's coils. Even tho my AC wiring diagram shows I will be using a 4-channel relay module, I might only install a one channel relay module. The resons for going to one channel is that I do not need a 4-channel relay module and I have other one channel relay modules in a drawer. +Since the Raspberry Pi is a 3.3V logic device, I use [3.6V Zener Diodes](https://www.amazon.com/Chanzon-34-Values-Zener-Assorted/dp/B07BTWBXJ3) for over voltage protection on the Raspberry Pi's GPIO lines when using a 5VDC power supply for the 4-channel relay module to activate the relay's coils.
