That’s a fascinating explanation of how it’s possible to run power and data in the same cable. I’ve been wondering about that since I first heard about it. Thank you!
I have been using a armour slice for years and love it! Makes life quicker and easier and guarantees a straight cut. However I tighten it down enough to make the non threaded part disappear then rotate it between 20-30 times depending on cable size.
Question for Doncaster cables. Why not make the DC cable which currently looks like satalite cable more distinctive. Maybe colour it black and yellow twist?
I live in the South East and you just can't get the Doncaster Low smoke. The 4mm stuff is like hen's teeth! The main wholesalers don't stock it. When they do claim to stock it, you turn up and then find it's been substituted for a different brand! Toolstation did stock the 2.5mm cable but they have stopped now! So unless the supply chain is sorted then it's just a nice idea. Great product quality but needs better marketing - IMHO. The same applies Tuff Sheath. Typically you end up being given NYY cable! Happy to be proven wrong.
EV Ultra Cable - Great idea and readily available. Could we have more than one data cable as typically you need a data cable and also two cores for a Current transformer. 1) I know you dont need all 8 cores for a network. 2) You could use Wifi for a network but I feel much more reliable to use a wired solution. Removes all the issues that can occur with Wifi security. Interested in what other people think.
You could use powerline networking instead of wifi, wired is ALWAYS superior to wireless, especially for stationary devices. I'd prefer to keep data independent of the power cable, it's more likely to fail over time simply because data is more sensitive than power.
@@technerd9655 and powerline networking well handy has security implications and practically needs to be set up like Wi-Fi. In the end it's easier to just run the cable. And while I'm here no not all 4 Paris are needed for 10/100 ethernet sort of. you need two pairs ( 4 wires ) for 10/100 and for gigabit and higher speeds you need all 4 pairs ( 8 wires ). Is a charger ever gonna be pushing that much data to need a gigabit connection no not yet. Although it would be neat if your car could download updates over the power connection and link onto your network hmmm. Edit: apparently speech to text now likes to change words after it gets the right word... Let's try fixing this again.
Been using an ArmourSlice for yrs but my understanding of correct technique is to fully tighten the blade onto the cable at the start and then the springloading of the jaw adds the required pressure as the cut is made..you'll see a non threaded section at the top of the screw part and the idea is you tighten until this is 'almost' fully hidden before starting your turns...no additional tightened required
It isn’t always out in the loft. Sometimes it’s out in the open. That said the more common thing to do if you’re gonna do something special is add a red cable, so you have a red and a black wire. You’re allowed to use weird colors, but black/red or black/black is industry standard for DC.
That EV Ultra with the builtin CAT5E cable should really be upgraded to CAT6 or CAT6A for long term standards support. However, having said that, despite the convenience, as an IT Pro, I'd prefer data cables to be totally separate from power cables because a data cable is more likely to fail over time, or simply be replaced sooner to be upgraded. Alternatively, powerline networking could be used instead. Also, 120V AC is NOT low voltage in anyway, should always be segregated from low voltage data cables.
When did education start to call it CPC and why. Google results. "CPC stands for Circuit Protective Conductor, which is basically the earth wire for the circuit and forms part of a system to join together all exposed conductive (metal) parts and connect them to the main earthing terminal" so basically still means Earth. I don't think old school will ever ask for Twin and CPC, doesn't roll of the tongue.
4:45 up to 1500 V ? Sounds high. Do you mean insulation rating, would not expect voltages anything like 1500V within a solar cell system. The 1500V rating of the cable covering would protect from other electrical wiring voltage potentials. On long cable runs the low dc voltage is increased by an inverter to a higher voltage to minimise transmission losses.
That fake cable segment was a real eye operner. The deliberate mistake. Is it the entry into the bottom of the CU. The tails and Earth/CPC not using the same stuffing glad?
I still don't understand their EV ultra cable answer where they say the nominal voltage of the two cable types is now the same. The voltage running on that ethernet cable is still almost always going to be low voltage DC, nothing like the same nominal circuit voltage as the 230V AC running over the other conductors. Sure the rating of the cable can be upgraded to say that it's designed to be able to handle 230V and tested as such, but it doesn't change the nominal circuit voltage.
I'm not sure about the Nominal Voltage comment? Nominal Voltage is the presumed average voltage in normal service, I believe. As the whole point is to prevent that what is the point of this? If this screening works why there ever be a need to protect against that ? Whatever is connected would probably be damaged if 230V travelled through it, so preventing the voltage getting through is surely vital
Trying to figure out the mistake on the wall at the end. The stuffing glad looks weird. I'm not sure about making data connections within the same enclosure although that's a CT so questionable. Is there a requirement to what color pair is used for a CT as it looks like they were using green instead of Brown. No wait I think I figured it out metal enclosure eddy currents.
That LS0F is prossibly from Turkey "Kable" which is atricious, and sometine the insulation will come away with the sheath when using the likes of the Jokari 30140 Twin and Earth Flat Cable Stripper

It might sound like a good idea, and if restricted to 10 base T (10Mbit) Ethernet or standard telecoms will probably work just fine. However as someone who's used Ethernet from its inception with 0.5" coax cable, it has always been a basic rule to avoid running Ethernet cable parallel to mains carrying ones ...

One thing is the fake cables now often use a CCA conductor, which is both a lot lighter and a lot less flexible, and more brittle.
A great show! Looking forward to the next one 😊

5:38 copper becomes stiffer due to work hardening, caused by bending not the passage of current. Heating copper will anneal it , removing stiffness.
The plastic will stiffen up with time, and you cannot heat insulated copper cable to anywhere near high enough temp to anneal it.

Also, 120V AC is NOT low voltage in anyway, should always be segregated from low voltage data cables.
Low voltage can be anything from 50V AC to 1000V AC the data would be classed as extra low voltage.
Also the shield on the CAT should also be ground on both ends.

1500 volts DC
When it comes to the enclosure, all of the wiring is correct.
That's the only hint your getting.

Sure the rating of the cable can be upgraded to say that it's designed to be able to handle 230V and tested as such, but it doesn't change the nominal circuit voltage.
I believe it's down to the insulation being able to resist 230 V where as data cabling is not rated for anything more than 50 V.
Is the deliberate mistake the Live and Neutral going through two separate holes in the ferrous metal enclosure potentially causing eddy currents?
I think it is. not sure if they would be significant?
Yep, I think it is the answer, vibration and noise would happen also

Maybe you want to discuss using NYM-J cable vs. Twin&earth ☺️
