ethernet and AC in conduit

I know it's not recommended or allowed by the NEC , but I'm wondering
if anybody knows how likely I am to have problems if I run ethernet
and AC (120 volt) in the same conduit for 20 meters....

thanks,
Steve

Unlikely to have technical problems BUT should there be a fire/injury and
the insurance company finds out they will void your coverage.

Thanks guys. Being in Mexico, anything I do is safer than what's
typical here. I just don't want extra trouble with my network
installation !

Do you want to bet the farm on that presumption?

None at all if you run the Ethernet over fiber.

If not, don't whine if your fire insurance is void...

hmmm - we ran the AC in the required conduit and metal boxes
to totally contain the AC/fire gremlins.

The "low voltage" stuff in the drop/plenum ceiling was a little trickier...
Either - it was the more expensive "plenum" cable, hung from the I-beams,
or run inside a pipe/conduit just for physical protection
and it would exit from the conduit at a patch panel on either end.

Same with the low voltage telco/phone wiring.... which you didn't mention.

Anyone that believes you can't cheat an honest man has never dealt with a
serious insurance claim.

And insurance company WILL bring in the hired guns for a big enough claim.
Been there watched it happen.

What would a "problem" be for you?

In theory, ethernet and 60 Hz AC won't interfere with each
other, so separation and isolation are irrelevant. Now, if
that AC is going to some noisy electrics (arc welders) or to
some sensitive equipment, there might be some interference.

But you are taking an unapproved risk and depriving others
of a layer of protection. Break the insulation, either by
a pulling scar or mechanical accident, and they are _much_
closer to a fatality. Do you want other people setting
traps for you? Don't set them for them!

As far as I know, it will likely work fine.

As you say, not allowed by the NEC. Some time ago, I predicted
that you could run ethernet with 240VAC common mode on the cable,
but I never got around to trying it. (Also not allowed by the NEC.)

Use cable ties onto the outside of the conduit.
