Review on M1A2 Circuit Breaker Switch 40A Waterproof Fuse Inline Holder 3-15 AWG Resettable Fuse Manual Reset 12V-48V DC For Car Audio Sound Amplifier System RV Home Marine Boat Truck by Robert Wells

Great buy for my audio rig - haven't (fortunately) tested its breaker rating but can say it's well built and the connections will withstand my 6ha. wires are perfect. The included screws are thin. So if you're going to put them in a spot that will rattle, I'd recommend getting better quality fasteners from your local hardware store. I installed it on a plastic surface using 3M VHB and so far so good.
