My observations are different: the fuse panels I see are almost all at least 50 years old, and most in the 70 to 90 years old range. Going strong. I can pick out newer fuses generally. Likely the ratio of current to the rating has a lot to do with lifetime.
Morning, Bryce.
Hope you are well and in good spirits this morning:-)

Fuses Frequently Asked Questions
How long does a fuse last?
If the fuse does not operate then it will typically last 20 - 30 years as long as it is operating within its design limitations.
If it is in a higher cyclic operating temperature i.e. very cold or very hot, then this can reduce its life.
Hope that helps.
