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.

Fridgie here. Just got some manufacturer training on some equipment that uses R-290 (propane) as the refrigerant and one of the interesting things in that training is that this manufacturer requires the use of wago lever connectors for any repairs on that equipment. They specifically tell you not to use any wire nuts or crimp connectors.

Why would they specifically require wagos? As far as I was aware the main benefit of them was ease of use and that doesn't seem like it would make any difference as far as the manufacturer is concerned. I especially fail to see how they could be more safe and robust than crimp connections. Is there something I'm missing here?

Yeah, just land that service ground wherever. It all ends up at the same place anyway, right?

Not one I've seen before. Trust no one, not even your helpers

Just bought a “new” breaker from Canada Breakers and its condition doesn’t exactly instill confidence. It looks dusty and used. The silver contacts are not shiny and have a matte white coating on them (I suspect oxidation?). Is this normal?

I am not an electrician, but an end user.

I am planning to build a very powerful server for running LLMs. It will have many GPUs and can realistically hit a 1500 watt sustained load. The PSU in my computer can handle 240v but I do not have access to a 240v circuit.

My question is whether it is a good idea to somehow balance the load between 2 or 3 120v circuits. If so, what are some methods to safely do this?

Cocky know it all apprentices, sure know how to bolt panels down
