I was a former mechanical maintenance tech for an auto manufacturer, so this story feels familiar to connecting a CNC lathe, or a multi-axis mill, but reading this guys ham-fisted accounts made me pretty livid.. >The datacenter staff, not needing a forklift in their day-to-day, had managed to solicit the services of a forklift, the associated operator, and some very handy folks to help navigate the mainframe from the storage space to its final location. Since this thing can approach the cost of a rolls-royce,and weighs half as much as a prius, movers and millwrights should have been called in. watching two chubby guys in tennis shoes and no gloves move a 700 kilo server in reverse would have given me a heart attack. > The various guides did hint towards how the phases are connected to various Bulk Power Regulators (BPR) but nothing was very definite. that should have been your clue to hire an electrician. there is no such thing as a bulk power regulator. this is a BUCK POWER REGULATOR. >I tried to do my best to construct a power cable Make sure you tell your building supervisor and the fire brigade you "tried your best." there is no "tried your best" section in the electrical code. You either construct a cable to spec, or not. >Now, I assumed that given there is no neutral it has to be a delta system Since youre handling voltages that can kill you, perhaps a meter? >The uncertainty was which phase-pair powered the lowest BPR? I guessed A-B OR your BPR explodes, your HV breaker trips, and you wipe out power for half the building. Christ on his throne.
