Can Screw In Fuses be Safe If Sized Correctly?
If no, why not?
If no, why not?
The one valid knock I would assign to thread-in fuses is the possibility of overheating due to a combination of poor contact and high currents.
One my electronics teachers introduced the basic concepts if voltage and current and power by way of recounting a barn fire that was blamed on a fusebox that had gotten hot enough to set the wooden wall afire, from which we learned of current and resistance becoming power (and heat)
Odd thing, is that a few years later, I hear a faint 'sizzling' sound in the basement of a house I was renting, and it's coming from a auxiliary fusebox/switch that feeds an electric water heater. Sure enough, the contacts for the screw-in fuses are burnt beyond redemption, and the little switch box was mighty warm.
I don’t understand how you come to this conclusion as a breaker will let through current in excess the rating of the breaker but an Edison base fuse will blow at the point of its rating.
I am speaking of compliant installation without any of the old tricks of defeating the overcurrent device. In my years of experience I have found as many 20 amp breakers on 14 gauge wire as I have found 20 amp fuses on the same.
FWIW, there are slow-blow fuses, too.

Was this just a test ?
This is awkward, but...
