I really wish you would try to keep up with the discussion, George. When a manufacturer marks it’s fuses with directional arrows it means they believe their fuses are uh, directional. When a manufacturer publishes detailed measurement data that shows differences in resistance depending on direction of the fuse it means the manufacturer believes fuses are directional. And not just fancy audiophile fuses; and not just fuses in DC applications. Every Yutz with ears knows that all fuses are directional. Wake up and smell the coffee! PS - It’s hard to see what your new avatar is. I’m guessing it’s supposed to be a loose cannon. Am I close?
