[c-nsp] 7609 6000W-DC PWR supply cabling Question

[William Jackson]

Hi all

 

The 6000W-DC power supply takes four pairs of 4AWG PWR cables, my
question is the following.

 

Which way is this setup cabled?

 

1.	all 4 pairs of cables going back to a single circuit breaker of
( 6000/48 = 125Amp )
2.	each pair of cables going back to a separate circuit breaker of
( 6000/4 = 1500/48 = 31.25 Amp )

 

I am not an electrical guy but I would have thought that the idea is
that the breaker trips before the cable burns, so I would assume option
2?
