Busbar
A solid metal conductor distributing high current within a rack or system, replacing bulky cabling.
Current numbers
50–51 V DCNVIDIA DGX GB200 nominal busbar output; actual voltage to ground and burn/arc exposure govern the task
1,400 ANVL72 MGX busbar current rating (deeper-profile ORV3-width bar, ~2x prior ampacity) — 1,400 A at 48 V is ~67 kW, so a ~132 kW rack needs parallel feeds
