The company I work for makes power infrastructure for data centres and the like, 3 phase 400v conductors, the smallest we make is 1000 amp rated and we go up to 6000 amp rated, that is a hell of a lot of power and we run 24 hours a day 7 days a week pumping out miles of these to power the data centres that run the internet so we can be shitty to each other

Gotta love them for giving us nice warm weather

One of the three is not like the other, in the way that it can never be eliminated. Let's play guess...
