I recently ordered some blade style circuit breakers from Narva, actually got the idea from a site I visit frequently:
Just installed them tonight, and I'll report back with how reliable they are. They're basically just like a regular fuses except you don't need to replace them. If a fuse blows, you just simply reset it after diagnosing the problem.
Old fuses that will be replaced.
New circuit breakers in, just waiting for the 5A one because it wasn't in stock.
