Phase rotation?
Maybe an attempt to create 6-phase systems.
Phase rotation?
480Sparky - Ugh. Let's deprecate those around us so that no one can discover that we don't know what we should. What a great way to foster cooperative working relationships.
LarryFine - maybe rotating circuit breakers? Since the loads are for apartments, I can't imagine that phase rotation would come into play.
JamesL - I bet all I get is voicemail!
480Sparky - That way they can wire up two 3 phase motors, coupled shaft-to-shaft, and they can fight each other. The invention of the perpetual non-motion machine!

If that is what he wanted then any drawings should have indicated what fuse to install in it as well.Amen to that. I installed "Horsepower-rated switches" for disconnects on some fractional HP motors in a commercial setting. Motors were pumps for the hot water heat system. I installed simple toggle switches that were rated for 2HP. Engineer said they were wrong. He spec'd "Horsepower-rated switches", and that what should be installed.
I said "They're switches... and they have a horsepower rating right on the strap. See?" as I remove the cover to show him.
"No! Those are NOT horsepower-rated switches!" he complained. I asked him to show me, specifically, what he wanted.
Turned out, he wanted FSUs.

I never wanted to slap anyone more in my whole life.

The final comma was the key to deciphering the text, it meant the final clause had nothing to do with the breakers. That plus the tense of "reverse," it was plausibly the command form.WWhitney (aka Wayne) came the closest. The note was a typo. It was supposed to indicate moving the entire panel to make access easier. However, they have changed their plans and are issuing a revision in which that won't be necessary.
Engineered and no drawings? No accompanying library of boiler plate specifications either?Drawings?![]()
