For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

I don't know enough about electricity. Electrician told me I have 3 phase 400v and it wasn't common. Not sure what that means or what benefit it gives me.
It just means that you can run industrial gear; maybe was owned by a keen potter previously. Big kilns need 3 phase power. No it isn't common for domestic, but I have a few friends with big shed that have 3 phase power for machining tools.
Depending on what capacity the supply has; e.g. if you have a smallish 80A supply you can run a a good sized CNC mill in you shed.
Three phase is useful for industrial motors or if you need more than 200A service. If I wanted to add another car charger in my garage and use them at the same time, they would have had to bring in another phase.
