Thanks for the info. I just ordered from Amazon a TekPower TP350 23 Amp DC 13.8V Switching power supply. It is highly rated and seems to have an 8 Amp fuse. It seems overkill, but the rating and the 8 Amp fuse seems to be adequate from what I had read up to this point.
Or do you think that the most expensive part of the system will burn to protect the cheapest part (the fuse) ? Just wondering.
