Internal or external fuse?
I assume an external fuse - and that might be the thing to check. Commercial wiring has usually a bit higher rating than home wiring, so they probably also have a higher rated fuse installed.
So maybe you have 10A at home, but 16A at work. Your toaster requires 15A, so your wiring at home is not good enough to support the current requirement. (That's rather the electrician installed a lower rated fuse, mathing the installation.)
