Just treat each phase individually. Most cost effective way is 6-20r dual receptacles with 6-20p to c13 y splitter cables. Cost will be about $70 to power 4. Just keep all 3 phases balanced.
This is what I was looking for. I guess I thought you had to use PDU's for some reason. I think I got caught up reading too many datacenter posts about 3-phase density.
Do I need to worry about setting up a system wide surge protection then?
