Being a non-electrical engineer (but an engineer in another unrelated field) I have a question regarding fusing.
If I have a 72V-12V DC-DC converter that is rated @ "50A", I assume the rating is for the 12V side -- correct? As such, I would attach a 50A fuse to the 12V output before the load and I should be good to go.
But for completeness, I'd like to add a circuit breaker the 72V input to the DC-DC converter. Because of the higher voltage, I assume I would need a much smaller amperage circuit breaker. Something on the order of 50*12/72 = 8.3A. Or approximately 10A. Do I have this right?
Thanks
