I don’t give a shit what anybody thinks, I’m wearing my arc flash gear if there is any risk. Let’s not pretend that connections are always tight and boards are kept in good condition. Most people do the bare minimum to maintain their equipment.
It's your life you could be playing with your dead right to assume the guy who worked on this panel was not as fastidious as you. The flash kit is in my opinion the only way to protect your self.
Spot on. Arc flash is no joke! I have seen the aftermath of a single phase of a 400v board that found earth. The panel was very close to the main transformer with a low impedance feed, so the copper instantly vaporised and the resulting plasma cloud coated everything within a half meter or so of ground zero in tiny bits of copper spray. The melting point of copper is over 1000degrees Celsius so the energy released into such a fault is huge. Stay safe out there!
Outstanding mate. The Chauvin Arnoux look way easier to use than the Fluke's 1738 and 434 that I normally rent for similar jobs here in Mainland China/Hong Kong/Macau. Need to see if I can source one of those to try out one of this days. I saw the video when you said you were going to start as a contactor and I will tell you, in this current climate you have them in place. But how professional you are and always striving for more I don't think it will be a problem. Both you and ØY Electrical's Cory are the two channels I follow and the two that, in my opinion, will be the example to follow. Keep up the good work.
It's an interesting game this one. Did my first one a couple of months ago to see if a company could move their 3 units across the way to some different units. To check if their existing loads would fit into the supply of the new units, or a new line from the substation would putting in. Good to see you back, and great edit on the intro.
Power meters should record real power only as that's what you are paying for. The problem with power factor is that it creates problems for the grid because you need a higher current and transmission efficiency is lower. Power factor doesn't really affect end users or their meters.
Commercial installations often charge for power factor as they have a bigger impact than a single residence. It's still good to check for overall as it's still wasted power. A lot of modern appliances also have active power factor correction built in
@@JamesTK Yes the supplier will require an industrial site to have power factor correction, or charge them for a poor power factor, but my point was this is not absorbed into power prices, you don't use more power from the meter. Power factor mainly only affects transmission efficiency, but heavy users will be penalised for have a bad PF.
Great video Mike, explained the process and the electrical theory behind it very well. Love to see you working safely and protecting yourself, looking forward to Part 2
I set up a PEL103 to measure a three phase 800A supply for a refrigeration unit. I wasn’t allowed to turn off the power and it was a bit stressful touching the bare live copper and trusting the the protective gloves
This was golden mate loved it, just had a butchers at those data loggers - gucci stuff. Cant wait for the next one! Get yourself an editor so you can smash out a few more regularly.
Thanks man! I’ve got lots of content coming up, not sure if in ready to hand over the process yet, I might just simplify it and stop being a perfectionist so it’s easier to get content out 😅 Next vid will be out in a week 🤝🏼
What arc flash calculator are you using? CAT 1 (4 cal) requires a hard hat with face shield and goggles + hearing protection. Your face shield alone is not compliant afaik. At CAT 2, which is probably where this board sits you need a hood or balaclava, the risk with that face shield is the arc front coming up under and concentrating on your face. I use the fluke 435s but to be fair these look a lot easier to use, i will be interested to see the results. Do you know if these will capture waveforms on transients, ie when switching supplies on a ATS? Edit, Hope you don’t see that first paragraph as negative, just a FYI, enjoy your vids and keep up the good work!
I used the electrical OM one, which come out at 2.15 cal but i may stand corrected. All the gear is CAT 2 but you make a fair point about the neck protection, it also doesn't have a chin strap either which isn't great, it's a lot better than nothing though but definitely has room for improvement. I've used the Fluke 1734 but these are a lot easier to get you head round, these PEL's only go as far as harmonics but something like the CA8345 from Chauvin will do transients and waveform. No offence taken on the comment, its constructive and every day is a school day in our game!
@@residualelectrical nice one, it’s good to see you using the gear mate, many people still bitch and moan about it but it is saving lives and you are a good role model to promote to the new generations coming in. A world away from how we used to do it!
did you see the news yesterday about that lad working on a pylon who ended up just about surviving with 40 percent burns from a 33,000v shock. they had him working too close to a live conductor. there is zero downside to spending an extra 5 mins to put a pair of gloves and overalls on.
Very knowledgable chap makes a change! I don’t think you mentioned checking to see if the phases are balanced which can cause your electricity bills to spiral out of control if not balanced…?? I suppose you’ll check it through the power factor of each phase to see if they’re equal?
Thanks man, that's a great point! the phases where unbalanced which may be a factor, the PEL 104 tells you the phase current and % balance on one of the pages which is nice, I've got some digging to do when i return!
@@residualelectrical yes many say it doesn’t make a difference but it does depending what type of loads you have….your a very thorough sparks and produce very neat work good for you!

100 percent right on mate

Great video, Mike! Health & safety and PPE often get overlooked, even on the simplest tasks. Keep up the great work, looking forward to part 2!
Thanks Ed! Been enjoying your content mate keep it up! 👊🏼
@@residualelectrical Thanks mate 🤝🏻
We need more electricians like you mate, any apprentice under you should consider themselves very lucky.
Very kind mate ❤️

arc flash gear is really needed even with these low voltages. You only need one flash to get some burns and better to have it then not.
Power meters should record real power only as that's what you are paying for. The problem with power factor is that it creates problems for the grid because you need a higher current and transmission efficiency is lower. Power factor doesn't really affect end users or their meters.

Yeah it can be a bit sketchy, I wouldn’t do anything I’m not comfortable doing if I’m honest, seen so many incidents from “peer pressure” 😒
2ow. In germany residents pay by used power, not the powerfactor
Same in UK, I think he just doesn't understand power factor only affect transmission efficiency on line losses.
Dependant of the billing agreement the landlord will be charged for the poor power factor or the KVar, as well as the energy they use..

I was under the impression that domestic electricity didn’t get any charge for power factor issues, but industrial could be charged.
Good stuff Mike. I look forward to part 2. Cheers
Thanks Jim, I hope you’re well!
@@residualelectricalcheers
Great video mate. Chauvin Arnoux do some serious kit! I've got their CA-6117 MFT and I'm still learning how to use it! 😂
I didn’t realise how much they do! I’m pretty sure that MFT can do real time power and energy logging too which is mad!
Henley carriers used to be 100 amp rated, recently (I say recently probably 4 years ago) they began down rating them to 80A max 🤷🏼♂️
we aren't slaves, this is a first world country. there is always, always time available to make work safer.
Yep!
Arc flash suit gives me flashbacks to working in Afghanistan on the yank bases 😂
cant just multiply by weeks as winter days are shorter so more lighting ect
Of course, AC will with run in the summer, gas heating in the winter etc, but it will give us a good indicator without logging for a whole year 👍🏼
Where did you get the gloves from? I’m in need for some for work and unsure of which to buy
These are CATU, have a look online 👍🏼
Balaclava is a good shout mike for your face guard
It’s on the list, hope your well Tom!
@@residualelectrical all good thank you 🙏

It’s out!
@@residualelectrical Thank you brother!
See you all in three months time
😂😭
A bit over the top donning an arc flash suit for that.
I disagree, but your entitled to your opinion Paul 🤝🏼
