NVIDIA DGX B300 power cord

On the AC/PDU version NVIDIA specifies the same cord family: C19/C20, 250 VAC, 20 A, 1200 mm (UL62 / IEC 60227 cord, IEC 60320-1 connectors).

The B300 AC chassis has 12 power inlets (12 × 3.2 kW PSUs). Each PSU needs its own cord. NVIDIA also sells a DC busbar version: no C19/C20 jumper, 54 VDC busbar instead.

Maximum current per AC outlet in the B300 intro table is 16 A per PSU at 200–240 VAC. The cord is still specified 20 A.
