I assume that this will still work in the long term. Unfortunately, I couldn’t get a circuit breaker with the same rating. The wire cross section should be similar to the mains cable’s cross section as it has to carry the same current. You can use single conductors, but as space is sparse within the shredder head, I opted for a two-core cable which makes routing the cable through the unit easier. I used a cable with a length of about 12 inch and later shortened it to the appropriate length. The cable must be long enough to connect the main board with the circuit breaker. As I couldn’t find a screwdriver with the appropriate length, I used a regular flat head screwdriver which was long enough and filed the size of the blade to fit the screws. The screw heads are all Phillips recessed heads. The screwdriver must be long enough to reach the screws which fasten the waste bin housing to the shredder top (about 6 inch, maybe a little more).

So this time I’ll show you how to open the shredder and how to replace the internal fuse with a circuit breaker. It also saves about 37 bucks (the price of a new shredder minus the circuit breaker) and it is environmental friendlier to repair than to replace. I could have just bought a new shredder and I really was on the verge, but I really love my Mailmate. The fuse blew again, and getting the shredder open just consumed so much time the first time that I decided to replace the fuse with a resettable circuit breaker. It took some time to find out how to open up the shredder, but eventually I got the job done and the shredder worked again….

I just love the size and design and the fact that it cross cuts (rather than just stripes) my documents, credit cards and CDs.Īfter some heavy use last year during tax preparation, the internal fuse blew. I bought a Staples Mailmate shredder some 6 years ago while living in the US.
