Yup. And even then there are differences here - 110v or 120v base, and the 2xx volt group has 208v, 220v, or 240v - both single phase or three phase. You want that in wye or delta? ;^)
This isn't exactly the only nuke plant they got. They got 56 of them. They got no spare parts or other reactors that are down that couldn't be cannibalized?
They had a lot of parts available with the same connectors. FOr some reason, they didn't get to the site with the problem. Hell, fly them in from half way around the world if necessary in 2-4 hours, don't irradiate square miles of land they can ill afford to lose.
Tell me about it, I am a maintenance supervisor at a concrete batching plant, the owners many years ago thought they were getting a bargain at an auction of some European machinery, I had to replace all the motors.
And then I modernized the whole plant to use 480V 3 phase as the cables and magnetic switches for 208 would have been too massive for a 100hp motor, I love 480 3ph. so simple to motor reverse, wires and switches much smaller.
I just did a google search, Japan uses 50hz, west coast is 60hz 100v, east coast is 50hz 100v, must be quite interesting in as such as clocks keeping time.
