Quite MY understanding. A 1 Ampere fuse @ 1 Ampere may well take minutes, or hours (or even longer) to "pop." @ 2 Amperes, maybe a few seconds. And I don't want to be around when a 32 Volt 10 Ampere fuse is used in (U.S.) standard 120+ Volts A.C. Much below 10 Amperes it MAY function OK, but much more than 10 amperes, (at any voltage above 32 Volts) look out! Shrapnel MAY result, but there CAN be an arc-over that keeps equipment powered long enough to cause irreparable damage. The MOST IMPORTANT thing to remember: "A fuse is meant to prevent a fire. " It is NOT meant to protect equipment. REPEAT AFTER ME>> It is NOT meant to protect equipment,just to prevent a fire. Most solid state devices will die from over or reversed polarity long before a fuse can blow.
