man that preheat galore. sound like a mega watt in power for lighting alone

Main hall in left image :
Assumed 2x40W fixtures = 100W/1 fixture (incl. ballasts)
30 fixtures in row
25 rows visible
=
75KW in visible rows

Side floors in bottom image :
Assumed same 2x40W fixtures
4 fixtures in row

29.6KW in visible rows

Anyone who has seen a full ceiling of preheaters flicker at startup can very well imagine what it would have looked like to see all of them start a once.

that still beyond a typical transformer going to residental house as most common is 25 KVA for all electric house.
but i have seen 75 KVA pad mounted underground wiring powering 8 residental houses all at once with A/C going in hot summer days.

I would love to see the start up of all those lights.

They of course would not have all been started up at once but rather section at a time.

I would love to have a video camera set up and recording during a power failure, in order to see them ALL start up when power is restored!! That puts my little 107 2 and 3 tube fixtures in my shop to shame!!

I would LOVE to be their electrical maintenance man! Would be a full time job just to keep em relamped! I see several that needed attention at the time of the photograph.

That's a great catalog! Definitely worth the download
