I have only worked with 220v single phase. Currently looking at a few places that offers 480v 3 phase.

Can anyone shed some experience on how i can  fully utilize the power.

1. How much work needs to be done, I plan to run 4x s9 per 208v pdu. So will need 10x nema outlets to begin with

2. Estimated cost ?

Most of the locations that i have seen are still being used by the previous tenant, and I see a lot of heavy machinery inside. Hopefully the places are fully set up for heavy loads.
