alt Hacker NewsI just haven't seen server rooms that don't demand a doubly sized neutral when one is required.
I live the NYC 208V life doing mostly resi, though.
Quick search of the spec for that is 6 power supplies, 2 of which are redundant. Looks to use a neutral to me. Says it uses C19/C20 connectors
edit: wait most ranges use 14-50R outlets and need a neutral ran. I am calling your statement into question. Surely harmonics and 120V internal draws cause non-zero neutral current. And I'm sure GPUs have harmonics being semiconductor flavored.
Turns out you are correct on both points!
My bad, NEMA 14-50R is a 4-wire receptacle with a neutral.
I learned something new today, 200% neutrals are not required by the NEC but can help with non-linear loads, and certain transformers that mitigate harmonics need 200% neutrals.
