Remember, NEVER use a multi-bit screwdriver in a live panel as the bits can fall out..
As you step away from your current task, you should always take your multi-bit screwdriver, knife, volt tick, and pliers in case you need to quickly diagnose issues if another trade asks for help. This Klein Tools 11-in-1 Multi-Bit Screwdriver was my absolute favorite for a couple reasons.. first, it’s not overly big.. second, the layout design really makes sense (I tried their bigger version, and could never get used to the layout). I highly recommend this Klein Tools Multi-Bit Screwdriver, which also has nut drivers built-in, too!
