Any guesses as to the likely voltage, amperage, and phase count running on this massive 3-conductor copper busbar system?
Found in an old factory. Decommissioned long ago, so I can't just poke it with multimeter. :)

We had a new factory 20 yrs ago with bigger cable troughs for fibre bundles as big as my thighs. Sorry just had to throw that in. this is for 3phase AC grid. and that is normal. – Tony Stewart EE75 Nov 17 '19 at 17:56

Can I buy the copper? – Tony Stewart EE75 Nov 17 '19 at 17:56

I’ve installed bigger bus bars then that! :) – Tyler Nov 17 '19 at 18:43

1"(it's off and thus) I can't poke it with a multimeter": and that feels somehow like a good thing, because this really looks like it would brighten the room right up should you drop your keyring, watch or screwdriver into one of the unisolated places :) – Marcus Müller Nov 17 '19 at 19:34

I have a wild guess regarding phase count, by the way :D it strongly correlates with the number of bars. – Marcus Müller Nov 17 '19 at 19:36

Also, do you have some size reference? It's a bit hard to guess whether these bars are 5 cm across or 2 cm. – Marcus Müller Nov 17 '19 at 19:37

Anodizing systems use big bus bars, 10,000s amps, 29 volts. – Tyler Nov 17 '19 at 22:38

@MarcusMüller RE phase count, That was my first thought as well, but couldn't it also be two phase with neutral? – bigjosh Dec 08 '19 at 03:09

1@bigjosh 2L+N: I think that's very rare in such high-powered systems, as that might actually measurably unbalance the grid around the consumer. – Marcus Müller Dec 08 '19 at 10:30
