Tape a drag line to the contact wire, push the damn contact wire up in
the frame, drill your hole without fear of nicking the wire, and pull
the damn contact wire back down.

Another method you can try is snaking the contact wire into a 3 or 4
inch piece of flexible conduit, taping it at both ends, throw the
conduit back in the hole, drill away without fear, and remove the
conduit when you're done.

You could also tape a chain to the wire, push it up, and use a wet
noodle to drag it back down after drilling.

This isn't very difficult
