Ethernet, Video and 12v AC in Same Pipe

[W. Watson]

I'm planning on running the three sets of wire in the Subject 60'
underground 18' deep in a 1 1/2" grey electrical pipe. The video is for a
video camera. Should I be concerned about interference. If so, what can I do
to minimize it? AC is black,white and green 12 gauge copper wire.

Shouldn't be any problem. I assume the video is run in shielded cable?

Since you changed the voltage to 120 volts AC.
I think that is against code in most jurisdictions.

You can't splice a 120 VAC cable in a buried conduit, however there is
little problem with interference if the video cable is shielded. Code
requires that the video cable be insulated against 120 VAC. Odd I know but
it's true.

Yes, shielded.

I haven't done video, but I have put eithernet, phone and 240 volt in the
same ditch. Both in different pipes, I fugured pipe is cheap, especially
when it gives you a little spacing from the voltage. I put the 240 volt at
30", back filled about 10" and put the eithernet, phone and video at about
20". The eithernet and phone is working fine, but I have yet to try the
video, it was cable TV. The 240 volt is a 100 amp service to my office,
located 138 feet from my shop and transformer.

Not really what you asked, but I thought it might help. Like I say, plastic
pipe is cheap, but the ditch is expensive. If you use a backhoe as opposed
to a trenching machine, you even get 15 or 20" apart at the same depth. In
my area code is 30" on the electric, and 24" on the phone.
