Over the past week, I built a small nichrome based 50 watt heater that
runs from 12 VDC power supply. It currently has 5 amp fast blow AGC
fuses in both lines, but what's to stop me from using a small circuit
breakers in each line instead? I see plenty of NOS or used ones on eBay
at maybe double the price for fuses, but not always the case as I've
seen fuse packs of similar price to the breakers.
