I need some education on fuse classes, meaning physical size and form factor.
(Tried uploading pic but the new forum software seems not set up right, anyway...)
I bought some 175A fuses not realizing that they can come in multiple form factors? I bought RK5 fuses, they are about 9" long, blade end to blade end. They are too big.
Turns out the fuses I'm trying to replace are about 7" long (blade end to blade end). The barrel is about 4" long and 1.5"-2" diameter.
I'm not easily finding what type of fuse this is. RK1 seem to be too small at 175A, or do I need fuse adapters??
The equipment is an FPE switchboard from the late 70s.
Please help! :dunce:
