Running Wire to Electrical Panel Box
Slow down on the hole size, unless using a conduit nipple the inspector will usually call more than 2 cables through a hole bundling (where 2 or more cables are run without spacing) so a massive hole for 8-10 ea 12 or 14 gauge cables just won’t work.
Next more than 3 current carrying conductors will require derating.
Drilling a series of 3/8 -3/4 holes is a better idea for most diy. inspectors don’t allow the proper derating of NM wire and it is easier just to limit the number of cables.
I have won the arguments in the past and even used bushings through a beam to prove the point (a nipple under 24” you don’t have to derate and you can run more)
As for running the wires there are 1 or 2 cable staples 2 cable are longer. Next there are wire stacking “staples” actually a nail that has spaced clips to run the wires along the studs. The cables need to be 1-1/4” back from the face of the studs and above the ceiling joist 1-1/4”
