Why does Renogy & Rich Solar recommend 60a fuse for their 60a SCC? Shouldn't it be like 70a?

When solar calculators points to a bigger fuse like 70a for 60a SCC.

I am the Noob around here, but my understanding is "NEC Code Calculations for Solar require a AMP factor of 125% (plus)" ...

I do not max anything out. I oversize wires and undersize breakers, fuses and lower factory limits to what I feel is reasonable. You'll get longer life out of the junk from China that is engineered by greedy corporations in the USA. It's worked for years for me.
