I am a consumer with very little electrics understanding. I have the 4CHR3 to replace a broken CHR2. I used to have a standard 3 core armoured cable wired in, and 4 x 3 core cables with plug sockets coming off it.
Now, I cant see how to wire up the earth from each of these cables? The Sonoff wiring diagram isnt really helping me. What do I physically do with the Earth? (treat me like you are teaching a noob - coz I am one! Thanks!
