My service ground wire goes through the cinder block/brick wall of my house - it's about a one inch hole all the way through so there's a pretty good draft. Is there anything that can be used to seal around the bare wire without having to disconnect it? I'm assuming fiberglass insulation wouldn't cut it. Just not sure what would/wouldn't be a violation or unsafe. Any thoughts would be appreciated.

You can use anything that won't damage the ground wire. Silicon caulk should be OK or you can use duct seal (duxseal) which would be available at an electrical supply house. The duct seal will remain soft & pliable just about forever which means it is easily removable should the need arise.
