Run cat5e/coax parallel to power conduit


I am in the process of rewiring my basement and trying to route all my cables using J-Hooks along the rafters in my semi walk in crawlspace. This includes running the cables to my new server rack. Problem I have is contrary to my request to have the power plugs up in the rafters, electrician mounted them under the rafters. Because of this, in order to get the trunk from one switch to the one in the rack, I need to run for about 4 feet, parallel to a power conduit. Outside of it, but still parallel to it until the cat5 and coax (Comcast box in the rack), drop down into the rack from the top opening. See setup below.

Right not cat5 is draping down to show it more visually, and can see in theory where I'd be dropping it vertically into the server rack. Didn't want to install any hanging J-Hooks in that area until I knew if it was a good idea or not. Technically have one sitting above the 30A plug if you can make it out.

I do have some Monster plastic cable wrap...

You have not stated any reason that would appear to prevent the obvious solution (if you consider it a problem at all) of running the network wiring along the face of the wall at the same level as the server rack, or roughly 12" below the power conduit. If the basement/crawlspace floods enough to flood the server rack you probably should rethink the location of the server rack, and in any case the cables being run horizontally higher up won't help a bit in that case.

You could also move the cables far enough forward into the room (3-4 feet, say) that they don't encroach on your shelving unit, then run them back along the joist (it's holding up a floor above if it's a crawlspace, so rafter is not the right term - those have a roof above them) to the server rack.

Despite a number of "trying to be perfectionist" scare stories about needing to keep network and power cables well-separated, the fact is that the differential pairs in Cat5 (or 6, or 7) are designed to reject...

We’ve all been there, you’re trying to build a nice settlement, but the power situation is just starting to get out of hand. So what do you do? You’ve got wires hanging everywhere, messing up the look and feel of the entire place. It’s time to make the switch to Power Conduits, and no I don’t just mean those silly things that have been in the game the whole time. Thanks to the new Contraptions DLC, Bethesda has added an entirely new group of Power Conduits to make use of, and this guide will teach you how to use them effectively to make your power pass through walls!

Create your Generator Room

The first step is to create yourself a Generator room. For the purpose of this guide we’re going to use a Fusion Generator, which provides a Power Output of 100. Plop down two or so floors, then go ahead and build up some of the walls around them. Make sure not to completely wall it in yet, or you won’t be able to work with it. With your walls and floors in place, it’s time to...

While we are on the topic, here is another thing I have been wondering about. Is there any advantage to using the so-called smurf tube versus the basic PVC stuff you would find at Home Depot? I haven't done a full-on price comparison yet, but it seems from what I have seen that that the smurf is pretty expensive. I am not sure why it might be better, other than it would be easier to make bends in the route. But if you wanted to make a straight run, for example from up in the attic down to a plate, it seems that a nice section of PVC pipe would do the trick fine, and maybe even be easier to put into place (assuming open walls).

ENT (aka smurf tube) is generally 2x as expensive as it's SCH40 rigid counterpart. ENT pays off in it's time to install. If you're doing the work yourself, it may not be worth it. In my opinion, it's ALWAYS worth it, money be damned! ENT uses mechanical "click lock" fittings to terminate into boxes or to couples sections of ENT. No primer or cement....

I have installed other types of low voltage wiring such as for automated devices and security installs, but never POE and was wondering about any RF and electrical issues involved. POE from what I understand can be up to around 25 watts using higher voltages than normal Ethernet. i.e. normally from 12 to 24 with a maxium of 48 volts.

When it comes to wiring, prior to installation, I usually first ask my self questions of any electrical issues that may be involved.

Question regarding e.g. electrical interference from other wiring sources, grounding, etc.

Types of wiring that may be suseptible to RF noise or produce RF.


Sensor wiring, for low various devices such as TTL devices, etc.

High voltage DC running ~150 - ~400 watt DC wires used with deep cell batteries and generators.

Low voltage cabling used with solar, wind turbines, etc.

For some types of installation such as with a mobile vehicle, running additional conduit...

I run an AV design / install company, so I design, spec and pull this stuff all day long.

You don't need to separate out low voltage signal cables from other low volt signal cables in a single conduit. If you are using decent VGA cable, the built in shield will be sufficient to withstand capacitance and inductance coupling to the other cables, or at least the level will be below anything visible on the VGA signal at XGA / VGA resolution. Also, do yourself a favor and use RapidRun style VGA / DVI cabling, which is industry standard and has a removable head whip for ease of pulling.

I've combined VGA runs with USB, ethernet, coax video + power for CCTV, fiber optic (which does need its own innerduct, but for protection, not shielding), and speaker wire runs. Granted, I don't usually spec for one conduit for all that, but if that's what the building hands you, you can use it without interference issues. This supposes you follow best...

This guide will show players how to use Power Conduits in Fallout 4, a new feature introduced with the Contraptions DLC.

If you’ve done any amount of building in Fallout 4, you know what it’s like to use a wall with holes in it, then run power lines all over the place trying to provide electricity to all the devices you have. It was a very messy system, but one that was appropriate for the state of the Commonwealth.

Those days of settlement wires looking more tangled than the ones behind your gaming PC and desk are gone. Bethesda has introduced Power Conduits, allowing players to run power through walls, along the base of walls, and all the way back to a central power source at your settlement. It still isn’t a perfect system, but it’s infinitely better and more organized than the old one.

Power Conduits

We’re not going to show you an overly complex way of using the Power Conduit system. Just like our guide for How to Build the Ammunition Plant in...

I have been looking into OpenCL for a little while, to see if it will be useful in my context, and while I understand the basics, I'm not sure I understand how to force multiple instances of a kernel to run in parallel.

In my situation, the application I want to run is inherently sequential and takes (in some cases) a very large input (hundreds of MB). However, the application in question has a number of different options/flags that can be set which in some cases make it faster, or slower. My hope is that we can re-write the application for OpenCL and then execute each option/flag in parallel, rather than guessing which sets of flags to use.

My question is this: How many kernels can a graphics card run in parallel. Is this something that can be looked at when purchasing? Is it linked to the number of shaders, memory, or the size of the application/kernel?

Additionally, while the input to the application will be the same each execution will modify the data in a...

Are Cat5e fully compatible with GBabit specification? What the main difference between Cat6?

Would like a proof if possible.


The main different between each version of the Cat specification is the numbers of twists per length of the cable.

Two wires running in parallel will create cross-talk. That is, if a current is running down one of the wires, the parallel wire will generate a current as well directly proportional to the distance between the wires and the current running in the wire. This is how a transformer works.

Twisting the wires interrupts this cross-talk, resulting in a cleaner signal as current running in one wire producese less of a current in the other wires. As signal speeds increase, the importance of cross-talk-free wires becomes more and more important and thus the twisting requirements become more and more stringent.

Cat6 has more dense twisting of the wires so that it produces a cleaner signal...
