I already have the stuff so I'm going to try to make it work. The thing I'm after is this...

1. How do I get power to 2 power distribution blocks so they are supplied power only when the switch is on. I already have power distribution blocks that always have power but want to add 2 that have power only when switched. I'd like each leg to support approximately 100 amps continuous use
