Yes, they conduct electricity. No, I have absolutely no idea if they work as advertised. As you probably know from this review, you cannot test a fuse, you can only trust the manufacturer's reputation. And there lies the problem with the fuses I got. Fuses from one order were marked "BUSS GMA" and marked UL, CSA, etc. The fuses from my other order had no such markings. Both were in small plastic bags.
