Is this a good idea?
Electrical Installation?  Me?
It's a big project: 25 solid state inverter drives for speed control, 5 new motor control centers a new breaker panel and a whole bunch of conduit.  Hey, this is the Process Improvement Group, our motto:
"One call does it all"
I had a small crew of five electricians and a working foreman to put all this in place.   Tear-out of the existing equipment took a couple weeks.  I didn't bother with any pictures of that as it's pretty boring.  What follows are a few pictures of some of the more interesting stuff.
A new pullbox with some serious wiring.
In order to use an existing feed, we had to break into some 3" conduit and re-route into a new I-Line breaker panel.  The left side of the box shows the three 500 MCM cables per phase incoming feed.  Going out on the right are the 350 MCM feeds to one of the new motor control panels. The 500's are nearly an inch in diameter, that's big wire!
New cables in the I-Line panel.
This is the box over the new breaker panel.  There are incoming and outgoing cables here. That's Chris' hard hat there on the bottom.  He's getting ready to terminate in the panel.
Here's Chris landing the cables.
It always surprises me that things come out as neat as they do when they start like this.  What a rat's nest!  It'll look fine when they're done.
All done, nice and neat.
Like I said, all nice and neat.  Cable ties and thinking ahead make everything looks like it belongs that way.
Now we're ready to feed something.
This is the new I-Line breaker panel.  I realize it doesn't look like much but those are 600 amp breakers in there, enough to handle three average households...each!

Let's go look at how we get this juice out to the motors.
