And where you have 277 you almost certainly have 480. But I suppose it is
possible to have 277 alone (is better to use than 120 for lots of fluorescent
lighting) or maybe even a 554/277 Edison style single phase split system,
where three phase distribution is not available and the higher voltage is
desirable for large areas of commercial lighting.
