Question:
Answers:
Most codes will not allow this and if you do this and there is a fire it will void your insurance coverage if they find it.you are better off just to dig another trench right beside that one and bury the other cables there...
you need to keep them separated by at leased 8 inches due to interference from the electrical field around the electrical wiring
I buried my cable tv line (coaxial) and my telephone line in the same trench as my incoming power. The only thing is my 220v line is in schedule 80 pvc. I have had no problems with interferance. You might need to find out if your local code allows this. My didn't, so after the trench was inspected I ran the other cables in with it before it was covered up.
you can do what ever you want to do. But if you chose to I would keep a few inches of dirt between them
If it's shielded.
I wouldn't do it though. I'd separate the trenches. Separate conduits. I'd put the cable in PVC. I 'd put the 220v in PVC.
I'd use 1" PVC for the cable. I'd also pull in a phone line and a garage door opener loop in the same 1".
