with regard to the difficulty we experience when connecting crocodile clips to earth bars and neutral bars its about time for manufactures to shape them differently or at least provide a test point on them

Watching sparky struggle to put the crocs on for insulation testing is a pain I am too familiar with 🤣. Great video!

Nearing the end of my apprenticeship and must say videos like this have really helped in my early years of the apprenticeship.. Thank you for the help!👍

Great channel im currently studying my level 3 and your videos are very informative. As someone new to the trade they are spot on, thank you. Haven’t looked at any other videos of yours yet but i hope they can teach me a thing or two. Not sure of your goals for the channel but educating/ talking through all the testing etc is great 👌🏾👍🏾

Not done any electrical testing since passing my exam last spring and have been searching the tube for full and descriptive run through me in live situations. You have the clearest, and most understable approach Thankyou Feeling more confident about tomorrow already 👍

I’ve got to say, absolutely love the detail, the quality of video and above all else the attitude to the trade. Wonderful, no nonsense and rightfully appalled by the quality of ‘work’.

Love seeing it in the real world keep these coming, 👍🏻

Dear sir,from a fellow tester.a superb video.very concise clear and very well presented.keep up the great work and great videos.well done.

Keep up the great work your almost at 10,000 views I have recommended your channel to my learners thanks GSH Electrical

Excellent video very detailed and informative helped me out massively keep them coming and thanks for sharing

A superb test sir.very thorough job.well done .keep up the great work and videos.I really enjoyed it.I love testing.

Best video I’ve watched in absolutely ages thank you!

your like a refresher course thanks for sharing your knowledge you should be teaching!

These luxury apartments are about 10 minutes drive from my home, can guarantee they’ll be an absolute fortune to buy/rent, funny to see the standard of work! Thanks for the detailed rundown, going to come I’m handy for my upcoming 2391 later this month!

Excellent video well balanced I totally agree with your decision not to remedy. I've been in the trade 50+ years and as soon as I saw the holes in the CU and then the dual sleeved cpc's / roughly trimmed 2'5 cables in the sockets thought 'crap'. Also with my other 'hat' on as a qualified plumber, flexi's on the expansion vessels are not allowed unless supplied by the manufacturers. Anybody remember a British Comedy from the 60's called "A home of your own" except this installation is not a comedy and those responsible should be made accountable.

Are these boards amd3 compliant? As the cover can be left in the open position?? Grey area? I have often wondered whilst looking at them

As an IT Engineer who does electronic soldering / motherboard repair etc as a side hobby, I can appreciate the pride you take in your work. I'll def be passing this onto my younger brother , who is an electrician. Keep up the good work, all the best!

Watched a lot of stuff on KZfaq re Inspection and Testing but this is the best for "as it really is" rather than a test rig in a classroom. Thank you and keep up the great work

I always use roundhead screws in metal back box's, stops the cables potentially getting caught on the sharp edge of the counter sink head.

Great explanation and clear guidance. Good job!

Very well demonstrated as always mate. Nice 👍🏾. I’ll be resisting my AM2 fault diagnosis as I’ve failed the first attempt. Just wondered if you could give us a possible heads up on some hints, tips and some knowledge of your own to help us out.? Much appreciated. Cheers.

Hi Ninja and fellow sparks. Other than properly gland off the supply SWA, what else could have been done to fire proof the board?

Really love your videos you would make a great teacher

Incredibly helpful and interesting. I especially liked the use of a socket for linking the L/N and L/E for testing the socket circuit instead of pulling the consumer unit apart.

Great video thank you for you help and guidance

Brill! It's great that you give loads of detail. 1 question though, is it the client that asks for the initial verification, ok 2, when and if the remedial work gets done, what's to stop them asking someone else to do the testing? Many thanks.

I wish I had this when I was at college great video. when doing the insulation resistance do you not have to disconnect the bonding cable?

How would you go about conducting an R1 + R2 test to confirm continuity of CPC on a lighting circuit with multiple recessed ceiling downlights? (50+ fittings). This is in the instance of a period inspection EICR not an initial verification. Would it have to be case of removing each down light and removing the cover to the connections to probe on? This would be very time consuming and very likely causing potentially damage to decorations etc. I have thought about conducting R2 wander leader lest to outer casing however there is no continuity to bottom of the painted can fittings. Furthermore a wander lead R2 test would not confirm polarity nor functional test of the switch. Interested to hear peoples thought and how they would or have done in a similar situation.

do you know what the plug shorting device is called? they look useful

brilliant work mate, clear & simple

For your IR tests could you not just have dropped the volts to 250V for the circuits with delicate equipment connected?

Question: if, for example you have a DB like in these flats and the disconnection time is 5secs for a TN supply head, then does this mean all final circuits from that DB have disconnection times of 5secs also? And incidentally what would be the disconnection time for the feed supplying the DB from the supply head DB, 0.4sec for a TN supply?

The video is lovely mate. Much oblige for competent people like yourself! Is there any chance of someone to accompany you on a few jobs to get into the skill more in depth? Lincoln

really interesting real world video, i am surprised that the designer placed the db in the tank cupboard. real chance of a leak causing some problems. is that a 2c swa cable sub main, what size is it ? i assume that a separate main earthing conductor is installed great video

Should you have locked off that main switch when testing bud, also , do the mains boards HAVE to be disabled hieght in a new build?? Thanks

Lovely video Ninja, as perusal. However, I’ve got a question for you? I’m sitting the 2391- exam in a months time and wanted to build a rig board for testing before I sit the exam, but seemingly my tutors attitude towards the suggestion is as if they don’t want to help me in such manner! I still want to build it as my exam is on the 25 of February and would like to start testing and recording results in order to boost my confidence. Please help if you can. Just need to know how many circuits you would recommend me installing and if you’ve got a spec, please? Thank you Lincoln

How did the building got powered?

Can someone answer me this please?! Regarding the cable that you rattle about in the wall - you said that it was not fixed/supported. How would one fix/support the cables in a wall. If one was clip them to the stuck then it might breach the permitted cable route zones given in the building standards. I am genuinely interested as I am an apprentice myself.

HELLO. I just want to know what is the box under the consumer unit, and where is conected that socket?

Hello ! I am from Poland and this video is a another useful as part of my preparation for testing and inspection exams. Thank you Sir !!!

Thanks for the video Why did you use 2 lead high and not 2 lead low? Why didn’t you use 3 lead low? Would appreciate the reply as I can’t understand this. thanks mate

Hi Ninja, because all the equipment had already been connected including lamps and down lights, would it be accepted on I.R to short the Live and Neutral and test against CPC? Great video's by the way. Many thanks.

My question is if its initial verification. How are you confirming everything in the tick boxes as you have not been there to verify this during installation. The only way I can see it being tested by a contractor coming in on another persons work when complete and energised would be an EICR. Then you would have no issues with things like IR as you do not need to test across load etc. I would personally go down that road list all faults problems classify them all give form back to main contractor for them to carry out remedial work. Retest and if all was rectified then issue another EICR with next date as 10 years or change of tenant etc depending on use.

Thanks for the video, very interesting.

Nice and informative video. Finally showing a real world situation that today's electricians face when being asked to certificate other contractors work. To be frankly honest it probably represents about 99.9% of every sites position when it's time to test. Unfortunately electricians both as employees and for that matter employers are usually under great pressure to get the electric on as soon as possible so other trades and use there power tools. Of course this should never happen and electricians must extensively explain why an installation should not be energised before all appropriate tests are completed. As a side note I look forward to hearing if you actually got paid for you time on that day. Keep up the great videos!

Hello ninja. Referring back to the megga Mft multimeter situation: there’s some on eBay which is already used, but looks exceptional. From experience, would you buy one from there or try and get it new?! Links

I know it’s probably a silly question, but could you not carry out a insulation resistance at 250V just to check it’s good?

nice double socket over the metal sink drainer is it for plugging in the toaster or kettle

A nice way to null out the plugtop test lead is to get a single unswitched socket on a ptrees box and link all the terminal out with some 6mm. All you have to do then is plug in your lead and null out the leads.

SparkyNinja Great video. I was testing a property other day & I use the same tester as you - my IR test (testing individual circuits) was taking a real long time. Battery life ok - leads seem fine, I was getting 999 or 850ish. Guessing this was due to some long runs (it’s a very large property, with Fuseboard on one side of house) ? Recently plastered walls ?

Just found your channel - because we exchanged comments on one of John Ward's videos. That was a very interesting video and raises a whole load of issues, in this case with the building industry. The very nub of it is 'accountability' and 'responsibility' - if you are the prime contractor you of course 'delegate' packages of work to sub contractors and with it the 'responsibility' to do it to spec. It does not matter how may levels of sub contracting that follow the 'responsibility' rests with the first sub contractor. However - you cannot delegate 'accountability' that is always latched to the prime contractor and cannot be 'slope shouldered'. At a practical level the installation electricians were clearly left to their own devices and were not supervised which is an abrogation of responsibility by the sub contractor and the prime contractor is accountable for allowing that situation to proceed unchecked. The site project manager probably needs a couple of size 10s up his or her arse! I am not an electrician - just a weary old professional engineer who sadly has witnessed similar stuff in lots of industries. The interesting juxtaposition is that this work has presumably been done by trained, qualified and accredited electricians - yet many sneer and warn of anyone attempting DIY household electrics - no matter their background, education and experience. Thank you for taking the time to put this together - I will subscribe and look at more. :-)

As a novice its was good to see you ring test at the socket with figure of 8 and not the fuse board as all other youtube videos show it done at fuse board. Is this the best way ?? Also high earth r2 reading was well explained. Thanks for great video

Mate can you confirm if you need to have a specific qualification to do EICR in Scotland.. nice videos.. keep up the good work..

Nice video. With you conducting the ring final circuit test at the socket outlet then the cpc reading could be affected by parallel paths at the consumer unit .

Continuity of protective conductors including main and supplementary equipotential bonding were not carried out first. This is always the first CHECK before energising Not ZS and PSCC AT DB....

Is having to crawl over copper pipes and a water heater to access the circuit panel acceptable standards there ? this looks very dangerous to me !

Wasn't there any low level spur controlled sockets for that kitchen ring circuit, my guess is that these would of had the highest R1+R2 readings.

How did your client respond to your report? Did the apartments ever get signed off? Are you going to do a follow up video to this one?

How did you measure Ze at landlord's supply without disconnecting main earth? Just curious

I'm an electricians mate so please forgive me if this is a stupid question but is there not a requirement for distance between sockets and sinks/baths because at 24:29 seems to close for my liking if I was washing up.

thank you, means a lot to a novice like me

Hi, So what happens next if you've been unable to sign-off the works as you've not been present on-site during construction, would the electricians that installed the installation have to sign-off the construction of the installation as being in accordance with BS 7671 and yourself sign-off the inspection and testing of the installation?

24:15 isn't that socket close to the sink is there a limit on how close sockets are to sinks, some would be more worried about the sockets under the sink

Good video. I'm an electrician myself. Quite frustrating to see shody electrical work. If electricians aren't going to do it right don't do the bloody job at all. Find a nother trade to botch up. Looking forward to your next video.

this is the UK? Incredible how many things sparky's get away with until a decent one comes along, at least you and Thomas Nagy are decent and won't take up a job unless you know how to do it correctly and if you are out of pocket because you underbidded then you eat it and still do the job correctly.

Being a PME shouldn't your PFC and PSC have the same ZDB? Or was the PFC lower due to to parallel earths? Just a student trying to learn

Is that calculation doing cooker continuity right? Were'nt you suppose to multiply 20 meters by 2. 20 x 2 x 10.49 ÷ 1000. Unless you use wandering lead

U taking any1 on locally?

my favorite convo debate do you really require a fan isolation switch local to bathroom ?

There's nothing wrong with the rear knockouts. They do not need to be sealed to comply with AMD3. You only need to maintain the correct IP rating on all surfaces. You're not trying to create a fire barrier

Hi Sparky. What to be an electrician but don't have any money and no experience. What do I do?

Two earths in one sleeve is one of my pet hates. I thought that practice had died out.

why do electrician s from the UK do resistance testing so often?looking for loose connection s??

what is a ring circuit?what is a radial?what is a spur?

Are you local to Whitley bay ?

Hello ninja Some very good pointers within your reply! To be honest. I will take your advice and stick to a proper manufacturer, even though it’ll be expensive, but that’s despite the facts, as my goal is the be excel within the electrical department and maintain long term. Many thanks. 👍🏾

Fantastic video mate ! Anybody saying that this is anal is no electrician. This a very useful learning tool. Thanks very much.

Mmm... one wonders quite what's going on in the heads of the installers/ testers. One hopes that they're capable enough (or they simply shouldn't be installing), but it would seem that their work ethics are decidedly dodgy. It takes little time extra to do things correctly rather that 'oh... it'll do', and they'd save themselves any grief PLUS their reputation as a conscientious firm would be intact. As you can't/ won't sign it off (quite right too), it may mean they'll lose out on the next development by that building contractor. Once word gets round that they're shoddy, they'll wish they'd done it correctly in the first instance. Thanks for the vid SN.

the best way to test our installation is to do and respect the protocol at every stage... and the voodo power is to love our jod because we bring the light to the pepeol house and house is our every think

If you take pride in your work its enjoyable, as soon as you let the quality slip you loose pride in your work and the job becomes a job, not a passion or something that can be fun. Id bin anyone 2minutes flat they leave that as their finished apartment. Also I never half ass the swa, I always gland both ends. Surface trunking the swa and gland on top correctly, not hide it like I see so many times.

you can short out L & N to IR , then use maintanance /function switches to isolate appliances, and IR, or IR at 250V

To be fair about the fire rating of the dB, I was told by manufacturers that if it is provided with knock outs, then the board is rated fire proof. All the nonsense about fire rated gland for each circuit is not required. The swa not being terminated is a joke though

If the armoured was correctly terminated at the other end and if you are relying on a separate earth and not the armouring for your main earth, would it matter if it wasn’t correctly glanded at the consumer unit end ? I know it’s good practice to do so but....?

Thank you

Did you know a 20mm brass bush fits a 13 amp plug perfectly for nulling your lead (niceic inspector showed me)

What a crock!! Good you turned up!!

Can I ask, does a 6mm t and e have a 2.5 cpc. Not a 4mm

Great video mate

MCBs are not metal so why would blanks need to be? Surely it's the CU lid doing the fireproofing?

Aren’t plastic covers fire rated for a certain amount of time?

I am not completely clear yet. Were you contracting from a contractor, or were you contracting from the contractor's contractor, or were you contracting from another contractor's contractor's contractor? We need to know. We have to know. We are desperate to know. Because it is just that critical to the video. TELL US!!!

Interesting video that I've enjoyed watching, surely the 'hidden' ring circuit JB must, in itself, be a cause for failure as I believe all mechanical joints are required to be accessible at all times for future maintenance purposes!

can you improve the sound, thanks

Just like to ask...As you say you are not on any of the schemes.....How do you go about signing off installations such as these? I presumed you would be a registered third party inspector? There is a document out there that advises building control of the risk of allowing a self employed electrician / inspector based on qualifications...so people may not actually have to join a scheme...they should enquire about just submitting the certificates directly to building control...and what the cost of that is.

Plastic blanks in a metal enclosure, ho no, same as the plastic in side and that of the MCB and the cable, all made from plastic. The IP of the enclosure is 2X or 3X me thinks, so that is more than adequate, ie the seal around the front wont keep out fumes/fire, like the amendment states as a requirement, so ALL metal enclosures unless they are IP54 or greater are useless? The enclosure is only supposed to minimise the escape of fire/fumes, in an attempt at delaying the inevitable, to allow escape.

Not an electrician but aren’t those sockets in the kitchen rather near to the draining part of the sink.

Does that swa need to be glanded if using a separate earthing conductor ?

As a U.S. electrcian, I do not think I could work in Great Britian, since the lingo is so different. And how do you get the electrons to flow horizontally in those horrible plastic panels ?

Can anyone tell me why having swa cable is a no, no to feed the consumer unit? Thanks

could u please list all the problems in this video and why it is a problem. i am not a native English speaker so i appreciate the help. ur videos are very helpful in learning the details of all the lower level works as i am currently learning MEP design. keep up the good work.
