Yeah 3 phase was sort of a must have for me. It allows me use 400v split to run my Syncrowave 350lx at full amperage without any power breaker issues at all. You should see the size of the feeder cables to my Syncrowave.
It didn’t happen all at once. I connect from the street to my house first with just the single phase connected at the house. Ran cable to the shop from the house and that sat unconnected for about a year. Than had all 3 phases and the shop connected with a 3 phase meter installed at the house.
Took a few years but thanks to the local electrical lines maintenance people and a local industrial electrical company plus a lot of trench digging and cable running by hand by me it all worked out.
