Type-S fuse adapters
Alright. Yay. Great idea. Tamper-proof. Can't possibly put the wrong size fuses in...
... except that the guy who "upgraded" with these adapters put 20A adapters into 15A circuits... So it is now not possible to use the CORRECT fuses.
So how do I get the adapters out? My research has shown that there used to be a tool for this. What does it look like, and does anybody still make one?
