Usually 480 > volt, many kVA. FWIW, do you imagine that's terribly large for urban firefighters in the big scheme of things, not just computer rooms? My memory could be wrong but I remember the John Hancock building, 60 stories, pulls about 1.5MW...I remember Boston Edison mentioning this in discussing a design I was working on of a supercomputer facility, that we were asking for more power than the hancock building which was ok but it presented..."challenges". Factories can pull a lot of power also (that room was never built.) Anyhow, once you're beyond a pea-shooter I don't think procedures for firefighting vary a whole lot, other than some outliers. -b
