Bruce:
Don explained the "no trip" situation, and Think Good spotted the Al/Cu wirenuts,
My two cents:
Have you attempted to contact the EC??
Have you contacted the builder??
Does your area have licenses for EC's? IF they do, that should be your first stop. Here in NJ, the State Board can be the consumers best friend.
The AHJ may be able to guide you in pursuing a solution to this situation.
