From Linda:

According to NEC code, 15A circuits can run continuous at 80% max or 12A.
I would set the warning at 11.5A, alarm at 12.5A to allow for momentary spikes.

EVB first, as Eric mentions, with a 2 minute delay. Since SEB 9 and 10 are powered by the same PDU, power them next.
Then I would start powering up the SEBs in order, 1-8, with a time delay that allows the current to settle.
You just want to get over the initial current surge before powering up the next unit.
Lastly, turn on PDU-4 machines with the same delay defined by the duration of surge current.
