Problems with Electrical Installation Wiring

My main question is whether I can reasonably lay the blame on this outage (and my burned out transformers) on the air conditioner installers.

Yaacov, I commonly try to stay away from arbitration issues due to my limited exposure to the projects of others and I understand your situation, so I will discuss this matter somewhat and hope that it will assist you.
