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.
You can't run 4 s9 per 208 30a pdu, they are rated for 5kW. Even my 240v 30a pdus trip with anything over 3.
Most PDUs split the incoming 30A in to two 15A or so circuit breakers. So you need to figure no more than two per circuit breaker of the PDU. Although 4 total is probably too close (counting inrush and possible high heat) as they run 6-7A per miner. Currently I have an S7 and an S9 on one PDU breaker and an S9 on the other. No plans to run more, once my M3s get here I wont run more than one of those on each circuit of my 30A PDU.
