I know it was just in the cable tester but would unplugging the feed end of the poe cable before snipping be safer as not to trip or damage the supply especially if it is not auto reset.
For wires that have to go through ferrous plates, going through a single hole will give lower losses, than having a circuit going through separate holes. Just like increasing the cross section area of conductors that carry larger currents, it is not just touches safety, bat also efficiency
Given that Annex ZB of 61439 offers us a fault rating of 16kA for type tested assemblies and a 100A fuse isn’t going to operate at anything like 100A I would suggest we have added an additional fire risk or at the very least a long slow overload and heating risk by adding a 100A fuse upstream of a CU that would not otherwise exist. Most if not all OCPD devices can handle 125A at their terminals so it really comes down to a busbar and switch issue. The addition of a fuse does nothing for us.
I have no time for an organisation that makes stupid and dangerous rules. Old 3 phase colours Red, Yellow and Blue Phase and Black Neutral - simple logical and easily identifiable in poor light. New colours (3 shades of dull) with Black now a Phase and Blue now Neutral. Just to make matters worse, you can have both in the same installation. Utter madness. Should have kept the old colours and additionally marked L1, L2 and L3 and told Europe to sod-off.
Question regarding EV Installations and the Regulation about in-built RCD's.. So IF the Charge Point has a built in RCD which conforms to the Regulation BS EN 62955 - Does that mean that IF I must install an RCD upstream to protect the cable then I can install a Single Pole RCD?
FI - Absence of product certification where an installer has built their own consumer unit? Not Type tested No evidence of testing or certification Options are C1 or FI As an inspector how can we know if it is safe or lethal without knowing the appropriate product standard and then accepting the insurance risk of the code?
If Rick fancies it we have a few solar jobs he is welcome to spend a week with us on. One in West Yorkshire, another in North Yorkshire. Both interesting jobs with different roofing systems, off grid capabalities and normal sparky work. We have biscuits....
It’s not just about people not liking change, it’s also about: badly managed change, bad training at colleges eg trying to pass people rather than create a better understanding. Also regulatory bodies are handing out approved contractor status to some horrific Sparks… none of that really nurtures a desire to keep up, does it?
No, it's about electricians firstly not accepting the new rules are a good idea, and then secondly moaning about how they have to spend more money on another copy of the regs (despite the amendment being downloadable for free).
The problem isn't training the regulatory bodies, it's training the electricians. Training? All they have to do is read the regs. But many struggle with that, firstly out of laziness, secondly many failed GCSE or O level English and find reading difficult. That's why they want someone else to explain it to them.
@@jameshansing5396 I didn't miss your points. I just told you other points that are bigger. Can't handle that can you? Is your narcissism getting the better of you?
@@efixx I read 62955 as requiring RCD Protection for any of the discrete DD,MD or PD variants. It seems a better solution would be to mandate the exclusion of RCDs or RDC’s from EV chargers and require it at the circuit origin. This would seem to ‘solve’ most issues. Lets get back to Commando approach of limiting it to a socket with all the kit elsewhere.
I would love to have a say, we have an issue where our documentation is used to allow makers of electricsl.equipment to design stuff that works with regs and uk. BUT example EV chargers are designed to work within uk DNO network voltages. Trouble is a hue problem is coming where ev chargers will only run at 253vac for 10 minutes then reboot because the network voltages are to high. Same with solar inverters. I am seeing this in my area , the ev charge company's were not aware off this issue until my phone call. We live rural and I am seeing issues with grid supply touching 262vac. DNO aware in our area. But ev chargers will suffer as they have no adjustment lime a solar inverter, inverter companyscare reluctant to up this voltage but it's possible. I have one to increase next week. Bern authorised to raise it by 5v due to customer seeing the inverter rebooting all day when sin is out. Who do you talk to about this .
Enjoying the channel, some really useful information you give. Have a couple of questions I hope someone will be able to answer. I'm building a new house and planning out the best way to get the electrician to wire the lighting circuits. I will be using 'smart' technology and wondered if a centralised (or star/spider) system would be acceptable under the latest guidelines? This would involve having a couple of large din rail connector 'junction' boxes where separate cables are installed to each light switch and light point, allowing centralised configuration (with clear cable marking and documentation of course) allowing switches and lights to be fully configured as needed (even allowing for a future conversion to a 'control 4' type of instalation if so required later on). My second question is, if the above is possible, could the enclosure for it be made of plastic? Or would it have to be metal? I would prefer plastic to allow it to also contain zigbee relays that won't really work well if contained in a metal box. I know there will a lot of people saying to stick with the usual lighting methods but want to build a modern house fit for the future. Interested in hearing peoples views.
I have used the same approach to lighting wiring in my own home using Rako modules. Keeping everything centralised and accessible makes set up and maintenance easy. You can use plastic junction boxes.
It definitely wasn’t going to be me to win as I was late turning in tonight. Also from what Mike was saying that the changes have filtered down from international standards and European unification . Why are The IET still adopting these standards we left the European Union on the promise that we will make our own rules regulations and laws .
What has the EU to do with the International Electrotechnical Commission other than having members on the committees just like the UK? We left the EU not the world.
Standardisation is a good idea. There was a time when nuts and bolts did not conform to a standard and things were chaos. The thing about Brexit and being able to follow our own rules was around the prevention of silly rules being imposed upon us, bureaucracy. Most technical standards are not about bureaucracy. There are clear benefits by adopting them.
@@nomennudum4592 How many pages does it take to describe the shape of a banana? So you think standardisation is not a good idea? Good luck with trying to justify that assertion.
I normally like your videos, but I waited an eternity for BS7671 A4 to be mentioned and gave up. Other videos are out there that are a lot more concise!

The debate is very focused on BS7671. Regardless of what BS7671 says surely the PAS recommendations is still worth following.
Correct as the new proposals wouldn’t come in to practice until 2026.
It's about time these changes to the regs where introduced, they sensible and over due
Two things that are definitely really Pink are Gary and Gordons boat races( faces) 🥵
Question regarding EV Installations and the Regulation about in-built RCD's.. So IF the Charge Point has a built in RCD which conforms to the Regulation BS EN 62955 - Does that mean that IF I must install an RCD upstream to protect the cable then I can install a Single Pole RCD?
It's getting like a phone update boring and fed up with the updates as the bsi ones ain't cheap but it's a necessity so what can we do
FI - Absence of product certification where an installer has built their own consumer unit?
Not Type tested
No evidence of testing or certification
Options are C1 or FI
As an inspector how can we know if it is safe or lethal without knowing the appropriate product standard and then accepting the insurance risk of the code?

@@deang5622 there should have been a comma after “training” my points are correct and valid
@@deang5622 think you have missed my points. Or just choosing to believe only you are correct. How typical 😂

According to 62955, RDC DD’s to 62955 STILL require an RCD as protection.
This change in Amd4 would therefore not change the position.
62955 - RDC -PD can incorporate both AC & DC

It remains a DNO issue. Under ESQCR regulations they have a duty to provide voltage within tolerance.
As I said before "Shall" and "Must" in standards are mandatory, not guidelines.
Enjoying the channel, some really useful information you give.
Have a couple of questions I hope someone will be able to answer.

The rules start at a global level with the IEC then filter down.
What has the EU to do with the International Electrotechnical Commission other than having members on the committees just like the UK?
We left the EU not the world.
Standardisation is a good idea.

@@deang5622 There never were any 'silly rules' imposed on us! Anyway the IEC is a bureaucracy and no worse for that.

I do wonder why there is an issue with a battery install in a garage, I'm can park a 100kWh car in there with no requirements.
would you see pink cables in fire alarm loops

Hi Tim, we have now added timestamps to the stream so you can jump to the topics that interest you! :)
44:00 - 😂 amazing
Agree with Tim Howard, informative and enjoyable to a point, but just not time efficient...gave up too!
There are timestamps in the description.
That's a 8P8C not an RJ45 😂😂😂😂😂😂😂😂
Very good
I had to do 400 RJ45s was a long day
As an apprentice 1 year away from my am2... Fucking new regs means i gotta do my regs exam again... Lol
No new exams
An electrician's input to any new rules proposed for BS7671: "It's a stupid rule. Why do we have to do it?"
Isn't that the truth!
Well done guys - the first IEEE PoE standard was 2003, so only 21 years late. en.wikipedia.org/wiki/Power_over_Ethernet
