Hi guys,
I'd like to what is a proper calculation for the incoming current sizing for the MCCB & power cabling ,for example, if I have 10 motors (DOL + Star Delta). Each motor for example running 20 Amps (3 phase, 415V).
Does that means my require current for incoming MCCB & power cable shall be;
General calculation:
10 motors x 20 Amps x 1.3 (Safety factor)
= 260 Amps?
Let's say we just neglect other small instrument power in the panel.
Thank you, guys.
