Those are cartridge fuses, (not circuit breakers) and I know when my parents moved to Michigan in 1954 that is the kind of "MAIN" fuses that were installed in our house.

Far as I know they are still installing them today.. Some places the code requires FUSES so it is common to install say a 100 amp fuse of that type and a 90 amp breaker (to protect the fuse).. I worked (40+ years ago) in a facility wired that way. (it was code then) .

They are easily found, any hardware should have replacement fuse cartridges.

All circuit breakers are tested and listed by Underwriters Laboratories and are re-tested during their manufacture. Some years ago, one of the (then) major manufacturers was caught falsifying their test data, and has been out of business since that time.

George I think you meant to say all circuit breakers ARE SUPPOSED TO BE TESTED, etc.

Alas,, IN this day of forged tax and approval stamps.. I would not in the least be surprised to find some made in xxxxx with false stamps on them.
