Cartridge Fuse Color-Code?

Yesterdays inspection had a combination fuse block/breaker panel. The fuses could only be seen through small holes in the block. The amp rating was not visible, but the fuse body was green. Do cartridge fuses have a color-code that determines the amp rating?


That size of fuse block would cause me to believe that those fuses are probably 200 amp . There is a color code that is manufacturer specific, within a certain time period. You can’t really tell much from a fuse’s color. Fuses from 60-100 amp are 5-7/8" long, fuses from 101-200 amp are 7-1/4" long, and fuses over 200 amp are 9" long.

Thanks Marc, Happy Holidays to you and yours.
