Two 12-4 Romex cables through the same floor joist holes
Hi. Can two 12-4 Romex cables be put through the same floor joist holes. The holes have about a 1 inch in diameter? They would run together through three floor joist holes for about 6 feet before separating and entering a junction box. I thought derating wouldn't apply since there are only 8 current carrying conductors.

The 12-4 I am using has a Red-Black-Blue-White and a bare(paper wrapped) Ground wire.
