I am curious to know what guidelines to use when fusing power
supplies. I have a machine with some small 4amp 24v power supplies. I
have placed breakers on the input side of supplies. I don?t know if
the current limit circuits within the power supply can be expected to
protect output wiring. I am mainly concerned with NFPA 7 & NEC, but I
would like to hear UL or IEC thoughts on the subject. The power supply
manufacturers I have asked don?t seem to know ? that struck me as very odd.
I'm not quite sure what you require, but you may find this helpful:
