I should have been more clear about the 9 @ 80. In reality that would be, 18 contactors @ 40 amps and 1 @ 40.
The boilers stay on line and are not starting up cold.
The average amperage draw is 43 Amps per leg 3 Phase
The contactors do sequence as per load demand

I have two brand new Precision Electric Boilers
Model # ST-30D-760D-480/150
PPh - 2593
KW - 760
Contactors are Furnas 42CF35AF - 480Volt = 40 Amp
Elements 38 @ 20 KW - 9 @ 80 & 1@ 40
Contactors 19
Just after three days of number 1 boiler being on line the contactors contacts are burning...
