I print out Panel Directories for all jobs, and if I have enough information for the connected loads [existing ones on Remodels / T.I.s], I'll also print out Color Panel Schedules.
On jobs where I have designed all, I'll include both Panel Directories and Colored Panel Schedules - regardless if I am the installer or if done by another Electrical Subcontractor.
I use Excel for these tasks.
As Steve [Sparky] has mentioned, placing your logo within a Panel Directory makes it both Cool and a Marketing angle.
This all can be done very easilly with Excel - which allows you to increase the cell sizes for the next person to easilly write in a newly added circuit description.
Most of the time I'll print up labels with the Panel's name and rating. I'll put a set inside and a set outside, then cover with packing tape for lamination.
Seen some really poor excuses for Panel Directories! References like:
" Receptacles", "Lights", "Computers", "Wall Partitions" and such.
Just do not mean anything when there's 5 Suites on a floor, or there's a ton of work stations.
