Not sure where to post this, so I'll put it here since making sure a cover is on an energized panel is 'safety'.
If you have a panel cover you need to constantly remove and replace, don't use the screws that come with it. Keep the original panel screws in a safe place.
Instead, take some short (3/4" or so) machine screws, nuts and wing nuts.
Install the screw and nut as shown here:
Then take your panel cover, place it over the screws,
and install a wing nut.
I use 8-32s for resi and most commercial panels. Large switchgear may need ?-20. No need to pull out a screwdriver or drill-driver... you can do this by hand.
The whole thing will cost less than $5 ($10 for larger panels), but easily save you that much in labor on the first job. When you?re done working in the panel and are ready to button it up for the last time, remove the hardware and drop it in your toolbox for the next job.
