How many wires?

[Twillows]

How many wires can I put through one knocked out hole in industrial panel board? All #10s 480v lighting panel board.

What's in the hole a nipple?

It's going to be a chase nipple or just a plastic bushing from a gutter below the panel board.

A nipple can be filled to 60%.

None. Wires must be installed in raceways and cannot be run through holes.
