"Use Magnet To Collect Shavings:"
When drilling into a panel box, take a magnet and set it next to the hole you are drilling. This will keep all the metal shavings from flying into the energized panel. Just remeber, it is a lot easier to remove the shavings from the magnet if you first put a plastic bag over the magnet.
