Security System: Update 1

I’m adding a circuit breaker interrupter to my home security system. The purpose of it is to completely turn off some breakers in the home when the alarm is in ‘AWAY DAY’ mode. The goal is to conserve energy by completely disabling certain circuits in the house. I have a lot of electrical vampires, things that consume electricity even when turned off, in my home. One example is our DVR. It draws about 50 watts even when it’s powered off. I don’t have any scheduled recordings, so it makes sense to disable it when it’s not being used. This is only one example, but one of many devices that consume power when I don’t need them to. As a result, I’m building a circuit that breaks the electrical circuit when we’re not home. If the resultant savings are a few hundred watts (that would otherwise run 24/7) it will be a worthwhile endeavor; particularly considering the introduction of solar power. Here’s a picture of the interruptor circuit:
