[QUOTE="Bird, post: 2705983, member: 211387"] What is the 3 phase Circuit Breaker Rating (A) for 205A DC amps ? My case: I have 8 units of Power Supply ( 30A ) 240VAC step to 12VDC and 128 units of 3.5" hard disk with ( 1.6A per unit ) 1. 1 unit of power supply shared to 16 units of hard disk ( 12VDC ) 2. 128 units of hard disk x 1.6A = 204.8A Total : 205A (DC) question: How much is the Main Circuit Breaker size (A) (AC) should i apply?
