Why is A2 of the switch in the middle (E321) connected to L3 instead of neutral? Shouldn’t it be neutral???
I think the switch is supposed to switch depending on whether there is 230V across A1 and A2. And the timer on the far right (E124) is supposed to accomplish this, the moment it receives “the signal” from my energy provider over mains electricity.
EDIT: Maybe A2 is not connected to L3. But it’s NOT neutral either. There is:
0V between A2 and L3.
230V between A2 and neutral.
400V between A2 and L1.
400V between A2 and L2.
That floating circuit breaker really ties the whole setup together lol. Do yourself a favour and clean this mess up before trying to reuse this old disused crap again.
But frankly it’s more beautiful this way
The charred remains of your burned down house will look really cute lol
