OK THW 2.5mm2 on 20A breakers will do the trick for your outlet circuits, run a green or green yellow 2.5mm2 for ground. Run 1.5mm2 on 10A breakers for lighting. I'd leave the 63A until it "fails" inspection, if the inspector is friendly, it could be "lubricated" into compliance For your pump you need NYY. Run 2 core if you put in a ground rod at the pump.

Could you post a clear photo (close up) of your two existing breakers please. 194V on a nominal 220V supply with minimal load is somewhat worrying! (already 12% low). Can you link to the spec. for your server rack please so we can see its power requirments.

Install a 3-phase incoming breaker and 3-phase board. Post some photos of what you currently have so we can be clear in our understanding. Run your existing board off one breaker + neutral in your new board (if it has a N-E link you will need to removed it as only one link is permitted in an installation). Divide your miners across the 3 phases taking account of the load on one phase presented by your house (how many miners and what type?). Pretty well any of the Schneider 3-phase boards will do the trick with a 100A 3-pole MCCB on the front. You will need a competent sparky to achieve this safely. Have you thought about the cooling load required by your miners? How do miners react to power interruptions? I'm not convinced that mining here is actually viable unless you have a lot of spare solar energy.

Thread is no longer relevant!

How much is your "little bit"? In a TNC-S (MEN) system such as we have in Thailand it's quite possible for there to be a small portion of the overall neutral current flowing through individual ground rods. Unless the voltage in question is significant there is no issue. It is possible that you are seeing a symptom of a poor joint in the neutral somewhere upstream from your location, but in order to know we need to know the magnitude of your "little bit" and what you are using as the reference point.

Beaten to it by 10 minutes! So.

I'm a Brit, once a week whether I need it or not

Could you post a screenshot of what you are looking at please?

Muang Thong Thani Spur Line site has been shut down for a week for "investigation".

Interestingly (or maybe not) we have a mixture of 300W, 340W and 380W, average size is 338W. On a per-panel basis we get about 1.1kWh per-day on average.

According to the photo, it's the world centre for pants flying at half-mast!

Weren't they going to use ankle-monitors at one time during COVID?

Two well-dressed ladies happened to start up a conversation during an endless wait in the Brisbane Airport Terminal. The first lady was an arrogant Victorian married to a wealthy business man, the second was a well-mannered elderly woman from Mount Isa, Queensland. After a little while the Victorian woman started by saying, "When my first child was born, my husband built a beautiful mansion for me." The lady from Mount Isa commented, "Well, isn't that fantastic?" The first woman continued, "When my second child was born, my husband bought me a beautiful Mercedes-Benz. Again, the lady from Mount Isa commented, "Well, isn't that fantastic?" The first woman went on, "Then, when my third child was born, my husband bought me this exquisite diamond bracelet. "Yet again, the Mount Isa lady commented, "Well, isn't that fantastic?" The first woman then asked, "What did your husband buy for you when you had your first child?" "My husband sent me to charm school," declared the Mount Isa lady. "Charm school?" the first woman cried, "What on earth could they teach you?" The Mount Isa lady responded, "Well as an example... Instead of saying, 'Who gives a F***?' I learned to say, "Well, isn't that fantastic?"

A woman walks into a drugstore and asks the pharmacist if he sells size extra-large condoms. He replies, "Yes we do. Would you like to buy some?" She responds, "No sir, but do you mind if I wait around here until someone does?"

Along with ringing a bell and calling "Unclean. Unclean." at regular intervals.

Well, here we are, April 1st. But the March production was no joke with daily production ranging from pretty amazing to amazingly awful. Note that we are now at 12.1kWp of panels from 03/03/24. This is our total daily energy consumption (solar + PEA). Family (grandkids) arrived from a snowy UK on the evening of the 28th hence the sudden jump due to 4 x teens (3F, 1M) taking 1-million-year hot showers and running the A/C at arctic temperatures. They are also eating us out of house and home Love them all really

Post some photos of what you have please, clearly showing the wiring and we should be able to work it out. I think you are going to struggle to find a 3-phase motor that is 220V phase-phase here, it's not a common configuration. A 380V unit that's star ("Y") connected internally could be modified, again if you can find one.
