DC Arc Flash on PV array
Although arc flashes hazards on direct current (DC) systems are just as real, they are often minimized or even ignored. Not only is it unrealistic to assume it is enough to take into account the incident energy in AC systems when assessing arc flash hazards, this in itself can be hazardous. For example, for a distribution panel that is fed by a battery room with a nominal capacity of 1000 ah, the level of calculated incident energy for the battery terminals would be 18 cal/cm². This high value requires protection with anti-arc coveralls for a standard work distance of 46 cm (18 inches). That’s why assessing arc flashes for DC systems is just as important to ensure worker safety.

Who just summoned the final boss up there
Always done, ... just how I was tough.
Don’t use alkaline batteries. Lithium batteries can also be dangerous but they don’t just rupture spontaneously.
Great, discussion I need do my testing qualification. Have left it a fair few years now. After hearing you discuss the ways of testing. It's exactly how I do it, removing parallel paths and doing calculations to know what reading your after also guides you to an issue. Just need to brush up on theory. Keep it up guys.
How will I get mire hands on electrical work that us the best ti get exoerience
An interesting subject, enjoyed hearing from Kirsty and John. I do find Paul talking way too much (he does seem to like the sound of his own voice) was distracting from the content on all these EICR videos. He makes an interesting subject harder to follow .
is it too much for the DNO to put a bloody label in the Cable entry point?
Amazing ,thanks again . These straight forward, follow along vids with yourself and your dad are priceless.
What caused this? Poor connection?
I found this very useful, even if a couple of older references since this was made - thanks for taking the time to do this :)
Superb, chaps - thank you 🙏
You look like you bum kids no diddy
Where is this?
There has to be an interview somewhere with a Napit CEO ‘so, you were aware of this particular electrician registered with your competent persons scheme had left unsafe work whilst also using logos on his adverts that were not justified, yet you still did not suspend his membership, or investigate the unsafe work, correct?’ “Yes that is correct”
Thank you both alot . I completed the 2392-10 as you and others suggested to gain a insight and now on my way to do the 2391-52. Your podcasts and videos are perfect .
Are these videos to do with the online multiple choice?
Image if someone tried putting it out with water💀
So dope!
Amazing mate thank you. Finally I get to see the effect of DC earth leakage!
I don’t know if you guys are still monitoring comments in 2024, but “Flyings” is a term I have encountered in the early cotton weaving industry, “Flyings” being of the nature of airborne lint, and obviously highly prevalent and combustible, and pointed out the need for “Electrical Plant to be protected from such debris”, I hope this helps - Julie
I was recently thinking how useful RNR2 is on detecting loose connections as R1R2 should equal RNR2 (minus switch lines).
Is an extra earth needed for a metal face plate? I would have assumed so (similar light switches have an earth screw to earth) but my new plug socket doesn't have an obvious earth screw for the faceplate
What exactly is the difference between 2392 and 2391 initial?
Thanks for this video Dave, this is the part I really struggled with as not used to having to complete drawing, only reading from them.
I know this was 3 years ago however, just a few queries... For socket circuits, why does the design guide consider the MCB rating in calculating the max. demand? 40% of 32A (12.8A) seems excessive for a domestic ring circuit. Another thing, that 40% factor used as diversity factor appears to be taken at the same time of the day for all the circuits. Has the time of utilisation been considered on that 40% figure? And this load assessment is just for a single dwelling unit. What about for a multiple dwelling unit? Can you please do another webinar video for that? Thanks.
Having no issues, but when i had my tails replaced my energy supplier for a EV charged install, he advised a C17 and as i was having a 100A fuse upgraded he advised me to mention it to uk Power networks as could do at the same time, UK power networks booked only the 110A fuse and when i have queried about the C17 black plactic, and upgrading it, they dont seem bothered just advise that if the electrician that changed the 100A fuse saw any issues they would have mentioned it, so showld i push for this to be replaced or is it fine, they mention there are some customers with older metal boxes.
Brilliant 👏
So... How exactly do you turn that off?
destroy the sun! well, more seriously, cut single cable before it and pull it away fast or cover the panels
@@ketas How do you cut a single cable without the arc killing you
Coming late to the discussion. One aspect not explicitly covered (as yet) was the generator 'reference' to earth and how / why that reference should be (or not) connected for (I believe) the elimination of human shock voltages (and if not connected the low currents that will/can still kill you ), rather than, as mentioned, what is considered the [lack of] power currents in the reference line, i.e. the currents would never blow a fuse or trip a circuit breaker. The aspect of creating a [mass of] earth reference protection can also be for the electromagnetic (radio) interference reduction that all the EMI/RFI filters in modern electronic equipments provide with their Y capacitors 'leaking' deliberately to their 'earth' / chassis. It also appears as it those in the US may have different views because of their own peculiar systems and operating environments with respect to protecting linesmen from back feeds from all the back up genny's in rural US.
UNLIMITED POWER
SPD should be installed by the electricity supplier
Very informative .... Amazing
Thank you Dear for this information
Hi. Thanks for this video. It is very useful preparation for the exam even for 18th Ed A2. In question 3, if the maximum voltage drop is 5V would that suggest a voltage drop has already occurred to the distribution board so the voltage at the distribution board would be 385V and calculations would then be based on that? Also, when determining minimum CSA would marks be lost by not determining Ct and applying it to the voltage drop calculation for 2.5 sq mm? Then if 15 V has already been dropped to the distribution board, the actual voltage drop would be 15 + 3.74 (18.84V) which is still acceptable (<20V).
Oh shit Thor stubbed his toe
Why not Join all three Earths to the socket earth rather than loop one ?
Fantastic content. Scares me to death!
Could you guys recommend a suitable tester for testing between the MET and the black cutout fuse holder.
Fascinating! Great podcast.
Great videos. Doing the 2391-52 next week and these videos have been a god send. Is there an outcome 5 practical video?
Dog shite installation pal I’m only surprised 1 , you even got your tester out after looking around and 2, you even turned up , as surely there self proclaimed install genius Sparky’s should be testing there own shit work, 😂😂 Keep up the good work pal ,
Incalculable amount of energy…wow…
You mean calculabe
I do take CPC's direct to the socket and then a flyleaf to the back box if a metal socket NIC didn't used to insist on on the latter ie if a plastic socket but NAPIT did. However the metal conduit system presents what I would consider a huge danger if relying on the metal of the conduit providing a CPC and in this scenario I encountered a situation whereupon the metal conduit had been severed and 2.5 had been used in between. Remember in galvanised conduit you are dealing with threads, cutting compound etc all of which can circumvent the continuity. My first flat had one of these infrastructures and I completely re-wired it again with singles but with a CPC within the conduit.
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.
Eew!
Funny enough earthing the back boxes is the most hateful, aggravating and annoying part of the job for me, I'd rather be pulling cables through inaccessible blind holes or bashing rock hard concrete. I have a full rewire in progress and all boxes, have been wired and finished... Apart from, as of this moment only half the boxes have been earthed. I did half and was expecting to finish off and do the rest next visit - Because I don't enjoy that bit, after hearing your very sensible and authoritative appraisal I was quite tempted to just leave them.. I mean the great Sparky Ninja has removed any guilt.. Of course it would be impossible for me to leave site without completing the blinkin' back boxes. Grrr. For some reason I couldn't do it. Excellent channel and what a great name too. Subbed.
