Great work. Simple. Cheap and effective... no engineer could ever design that.
Lol, j/k I make friends with engineers pretty easilly at work, I'm that type as well, always designing, I love it.
Back on track though, for anyone else who may want to make one of these, try wiring a heavy duty relay in line with the timer, you can get a SPDT relay from an electrical or electronics supply company. With one of these, you can up your amperage rating on the timer, as well as turn a NO timer into a NC timer. (change a timer that normally has the power off, into one that normally has the power on)
That being said, my post is for purely educational purposes and suggestions of ideas to competent electricians, if you have ANY doubt about your skill with the zap juice, then find an electrician to wire this up for you. I can draw up a schematic that should give the gyst of the circuit I'm talking about if anyone's interested. In the meantime rock on with the DIY!
