Questions about this item

What is the maximum operating temperature before the insulation fails?

The nylon insulation is rated to 221 degrees Fahrenheit, so sustained heat above that point will degrade the material.

How much heat does each connector dissipate when carrying full rated current all day?

These are passive copper terminals; they generate no heat themselves, but resistance at the crimp joint will warm the wire under continuous 600 V load.

What crimp tool and wire gauge must I already have to install these terminals?

You need a crimper suited for butted-seam barrels and stranded copper wire between 16 AWG and 14 AWG.
