as an electrician, looking at how you installed your wiring makes me bite my fingernails! nowhere near min. code!! for those wires to be exposed like that they need to be in conduit. and why are you using 3 wire nm into the breaker box? if you plan on hooking 2 hot wires up to one neutral wire your going to have major problems with induction heating. i see fire written all over this.

that isnt a chopped up extension cord going into your timer box is it??
