ahhh..what IS he trying to do...

Chris is right in the fact that you should try to keep the voltage up and
the curent down, but now its the distribution side of a transformer.

The feed is 480V/277 Wye but I need around 2000 Amps of 120VAC. Yep, heard
me right.

So, the plan is...HIRE an electrician to tap off the feed, into a
disconnect, and then from there, feed to a 300KvA transformer, which
generates three legs of 120VAC, single phase. Each leg can supply up to 833
Amps.  From the transformer, it feeds several 200A subpanels.  The neutral
is double sized, to handle currents because non-linear loads.

Its the distribution from the transformer to each of the panels.

My thoughts are to use a busbar of sorts, or some large piece of Al that is
drilled and tapped for the connections of the 4/0 wire.  I was just working
on how to go from the transformer to the bus bars (solid Al or copper I
suppose).  Distances will be SHORT, very short...

And its all a temporary installation, up for about a month.  The only safety
issue is from the transformer distribution to each of the panels, but it
might be under a raised floor so hopefully will be out of sight, out of
touch...
