The building where this equipment is located was purchased 'as is' and made to work for the current occupants. Some of the old-timers that stayed on with the new company had been here 30+ years. So the building and electrical systems are at least that old. There are many other issues at this location that are on the "to-do" list and they are being taken care of. After seeing the start-up of other locations in pre-existing structures it surprised me that this wasn't addressed early on. But it is being rectified now.
