The ground fault breaker (RCD by you) on the 480V
supply the work's main
datacenter (which is rated at 1MVA, or 1200A currently - an upgrade to
5MW is coming this year) was tripping on us when it was set to 200-300A,
Dop you mean that? 200A (not mA) of earth leakage wouldappear to be
dangerously high in any installation.
