I was drilling a hole for an antenna wire and hit a wire inside the wall. Of course this flipped the breaker. But after splicing the damaged section of wire, the breaker no longer works. Bought a new breaker and after several hours, discovered that the left hot bus bar no longer works. As in every other breaker no longer works. The breakers on the right side that feed from the left hot bus bar don't work either. Any ideas? Thanks
