Couldn't really see the appropriate category, so I'm going with this one. Can anyone tell me the answer to this question:
Is an 80-amp fuse strip thicker or thinner than a 40-amp fuse strip?
Thank you, Sand

 

You wouldn't necessarily be able to tell by the physical size; you have to go by the manufacturer's ratings.

Just so you know, fuse design is not an area for amateurs to dabble in. A fuse is the "last line of defense" before things go horribly wrong. A badly designed or improperly selected fuse that tries to break a mains circuit can turn into a blazing plasma ball, devouring anything it touches - including humans - faster than you can blink an eye.

You mention 80 Amperes, but you didn't mention your application - are you dealing with low voltage (under 50v) DC, AC, or high voltage AC or DC?

Is this an existing fuse panel/fuse holder, or are you trying to plan for a new application?

 

Hello,

Do you mean these?

The physical size is not the only difference.
The material can also be different.

Do not experimet yourself with some strips, leave that to the manufacturers.
They have a lot of experience and test facilities.
