electrical wiring question- finishing basement

So I have a large, open great room. There are a total of 19 lights on four different switches. The switches are in two separate 4 gange boxes with three way switches. Because there are so many lights, I decided to run two separate power feeds from the electrical panel to cover all these lights. My question is- is it legal to have two separate powered feeds entering a 4 gange box? I would use one power feed circuit on two of the light runs and the other powered feed on the remaining two light runs. I would keep each powered circuit separate inside the boxes. I just wasn't sure if that was allowed or not?

Welcome to the forums.

Normally you would use a multi wire branch circuit. That would be a 3 wire circuit with two hots and a common shared neutral. Running two independent circuits to that box is also perfectly acceptable. The hot and neutrals will remain separate. All the grounds are tied together.

When I know there is more than 1 circuit inside a box..... I write the two circuit numbers on the back of the switch plate.

In your case... you could write the circuit numbers down on both plates.

It is perfectly fine to have more then one circuit in a box. In commercial I have seen over 40 circuits in a box, but that was a 6x6x48" gutter.
