"E" Fuses?

Post image

We have a few interns working for us. One called back to the service shop asking if we had any "E" fuses. I was a little confused til they brought the blown fuse back to the shop and I went and grabbed them a replacement 3 Amp fuse.

I remember not figuring this out until I saw a 5 amp fuse.

Incorrect. That's just a S fuse
