Decent quality but I'm not sure I'd trust them at 30 amps
I needed to add a blade fuse to my Jeep to power my new refrigerator (which is about a 5-6 amp load). These were inexpensive and looked decent and I can always use some spares around. I have doubts about the wire actually being 10 gauge and the fuse holder itself is typically cheap but for my purpose it's excellent. I only left three stars because again, I wouldn't use this at 30 amps.
