Glass fuse -color code-can't read fuse rating.

[Big Bill]

I was looking over this old style auxillary panel which had a couple problems including over-fused circit, and a double on the feed side of the panel leaving it un-protected. When I observed one of the glass fuses the fuse rating was'nt legible and it was gray in color unlike the 15 and 20 amp fuses, blue and red. Can someone simply list the colors of the common glass fuses? The local home improvement didn't have a gray fuse...I've searched the www to no resolve...Thanks, Bill O

Interesting, never seen one.............

Thanks.

Thanks for the help! hard to believe this amateur wiring job had a 10 amp fuse in it, but the color was a little un-defined and if one puts a penny behind it it'll save a trip to the store and $1.65...

Actually, putting in a smaller fuse is safer. Perhaps less convenient for the user (if it repeatedly blows), but safer. It's putting in a larger fuse (or a penny) that leads to danger.

If you can not read the fuse rating in the glass,the rating is stamped in to the nipple at the back of the fuse,were it is in contact with the bus bar

That's a good tip. I just tried it on some of the fuses in my panel. On a lot of them, it was difficult to read the number because of all of the black carbon & pitting. One was especially easy to read though. It said, "In God We Trust, Liberty, 1984."

Yes, that would be a "Lincoln" fuse. They are rated at the melting point of copper.
