There should be no problem doing what you want, as long as all the conductors and overcurrent devices are sized properly. As per National Electrical Code, you'll size the equipment grounding conductor (EGC) based on the largest overcurrent device used. Which means the EGC will likely be sized based on the size of the breaker protecting the 240 volt circuit. ...
The recommendation I had received was run several lengths of string along the cable run. The idea being that you can tie the string to new cable and pull it through. Obviously this only works on certain kinds of runs.
Empty conduit is your best bet here. No point in guessing what (if anything) you may get, and guessing wrong. While you can leave a pull string in it, you can also just vacuum a pull string into it when the time comes (that's what is normally done to get it in in the first place.) If you do leave a string, don't worry about how big/strong it is - it can be ...
Could you put a couple intermediate "manholes" in the path? So instead of one 200m pull you have 3 or 4 shorter runs? You'd still run a 200m cable, but this way you only have to pull it 50-65m at a time. I'd definitely run at least one, maybe 2 empty conduits - it's a lot easier to run an extra conduit now than to re-trench it later
The best future proofing you can do is over-provisioning the amount and size of conduit. Pulling a cable through a relatively straight 200m run is not out of the question especially with proper cable lubricant and a large enough conduit. I would suggest not pulling anything like fiber without proper specs on the gear on both ends. There's a good chance ...
No, you cannot. Unless you're not covered by National Electrical Code (or similar), you don't care about following codes, or you're also installing a permanent barrier or listed divider. National Electrical Code Chapter 8 Communications Systems. Article 820 Community Antenna Television and Radio Distribution Systems. 820.133 Installation ...
