I'm having a generator installed. The electrician is running the wires for the supported circuits to the transfer switch and drilled a large number of holes in the top header (not sure correct name) and a very large beam). The garage is very tall so it has a beam a few feet below the top of the wall. He said it was only 3/4" holes but there is a 1" hole and a couple of holes are right next to each other. We are in earthquake country and this really worries me. I asked to run conduit like the they did for the solar but he didn't want to do that. Please see pics and tell me what you think. Thanks.
