Here's a shot of the main disconnect for the system as well as all the branch circuit switches. The box on the back contains 15 amp breakers to protect against short circuits. Has a few wires burn up in the past before I installed it. And yes, I know most of the equipment shown here is not designed for outdoor use, but raintight boxes were too expensive and it's worked fine this way for over a year. Plus I got the Siemens 3 phase disconnect for free!
