We have (2) 2" plastic conduits buried from the garage to the back of the house. Where the 2 conduits come out of the ground, they go into a 8x8" weathertight junction box on the rear of the house.

1 conduit has 220vac
1 conduit has 3 siamese cables for security cameras and 1 cat5 phone wire
The siamese cables have 12vDC running through them.

My question is: Is this code to have both 12vDC and cat5 phone wire and 240vAC in the same junction box, even though they are run in separate conduits, or should each be in their own separate box ?

The holes are not run into the house yet for the wires, but I assume separate holes should be run for the 220v and 12v to enter the home from the outside weatherproof box.

If the box were fitted with a divider to keep separation between the two voltage level it would be possible. I have never seen a 2 gang WP box that had the option for the divider to be added.

Use two holes at the house for the wiring. I would use an LB to go into the house instead of that huge junction box.

Thanks for the replies.
My bro n law will have to seperate the box some how.
I wasn't sure if this would be code or pass inspection if it came to that.
I thought 12vDC should be run in separate boxes and not combined all in 1 box with house current wires.
