Review on M1A2 Circuit: A Reliable Waterproof Resettable Amplifier for Industrial Electrical Applications by Scott Welch

Great buy for my audio rig - haven't (fortunately) tested its breaker rating but can say it's well built and the connectors stand up to 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.
