I'd have to look, but from the OM, there's a couple sizes. I'd assume micros and minis for the most part. Micros are tiny. Mini's are small but have semi-pointed blades.2500HD question...What type of fuses do I have? I look at these things and they all look the same...I need to use a fuse tap and need to know what type to order. Thank you in advance for this dummy question.
The standard (ATO/ATCs) you see in trailers and generic fuse blocks are fairly big, they're easy to tell apart from the minis not only by size, but the blades are almost square.
There are cartridge fuses, where the body is like a cube, but I don't expect you'd be tapping those. Most OEs use cartridge fuses instead of higher amperage Maxi's.
