76 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide
Table 20 (page 76) lists the basic AC power requirements for a 60-amp,
three-phase XP1024 R1 DKU.
Table 21 (page 76) lists the basic AC power requirements for 60-amp,
three-phase, R2, L1, and L2 XP1024 DKUs. Unlike the first DKU (R1),
DKUs R2, L1, and L2 do not provide AC power to the DKC.

2. 30-amp breakers are adequate at 380, 400, and 415 Vac, because the current
drawn at these voltages is considerably less than at the lower voltages.
