300A Aluminum MC Cable Feed

[mstrlucky74]

Need a little help. Need to feed (3) 300A 3P4W bottom troughtemp panels. From a 2000A board that is 350’ away. The panels are on the 6^th,7^th and floor stacked above each other. My questions:
Would you run one feeders and tap in each trough or threeseparate feeders?
What size feeder would you run( individual runs looks like#750) in the given whichever scenario you choose in question #1.
What size switch would you use given the scenario above.

Unless you know that the neutral is going to have a high non-linear load, I would not use the 750. I would use a 500 with a 1/0 bare to comply with upsizing for voltage drop. That size is available from Southwire, the cut sheet I have saved on my computer lists many more option than the one you provided.

I would also use 500 for 300 amps. Might want to confirm availability before finalizing the design. I recently wanted to use that same cable but went with PVC and individual conductors due to availability and minimums
