I teach high school physics and electronics. My experience is that no amount of instruction prevents students from accidentally blowing fuses when they're first learning how to measure voltage and current in a circuit. I would love to buy a classroom set of these: http://www.industrial-needs.com/technical-data/images/multimeter-metrix-mx24b-fuse-box.jpg but can't seem to find them anywhere. Does anyone know of something similar or where I can get these? Thanks!
