A couple of years ago we were demolishing two of our buildings at work which housed large technical facilities so each building had its own Ring Main Unit to isolate it from 11kV ring going round site and a dedicated transformer feeding each buildings switch rooms. When SSEN came to remove the RMUs and transformers they isolated the HV network further back on ring. So how do you prove an 11kV cable is dead before disconnecting it from RMU? Turns out you clamp what looks like a chisel to the outside of the cable, insert an explosive charge and pull a string to detonate, forcing said chisel through the insulation to short all the conductors together. What a fun day that was!

[@Ornithopter470]

At least stateside, it's a literal nightmare getting to the point where you're doing this sort of thing. Unless you're a licensed master electrician, you're going to be stuck doing most of the crappy parts of this kind of work. For every little comparative money, for a very long time. It takes longer in the US to become a master electrician than it does to become a nurse. He also cuts out most of the really unpleasant parts. Like getting the cabling in place, or cut. Not to mention doing this sort of work when it's 85+ degrees Fahrenheit and 90% humidity is plenty to get a lot of people out of the field pretty quick. Why would you WANT to work in godawful conditions for average pay at best?

[@thetomster7625]

@@Ornithopter470 simple answer: because you see what you have done at the end of the day... I only create a bunch of paper/data and hopefully every half year or so an actual finished design step, which is then printed and produced. Start to finish usually takes us - in my field of work - about 3 to 4 years. Its very hard to see progress in that kind of environment.... so most days are full of work and meetings that leave you brainfucked and you can't tell what was acomplished. don't get me wrong: I enjoy my job, its interesting, challenging, pays well and actually fun, most times. but getting home after only a couple of days, having finished something good looking as this, just lets you sleep better. and ultimately, this is sometimes more important, then making a little extra money. Also: Obviously I can't speak for the US, but in Europe (UK, Germany, etc) this kind of work actually doesn't pay that bad and its easier getting to a point where you are a master. There is a huge shortage of labour workers here and thus they can make quite big prices these days - so: get over here and enjoy the craft as its supposed to be :)

@@randacnam7321 Quite frankly the US colour system is hot garbage so let's not even bring that up, most of all with cross-country compatibility. That's your opinion, okay, completely ignored what I said, that's fine but just think for 2 minutes. Like just for starters what if you end up with a UV damaged cable? Something can become white or grey in the summer sun of 10 years so it's an absolute no-go for a neutral colour, if it can be a faded live. Also yellow-green is the best thing for earth because that's the only patterned cable. Also blue and green fade the same way in the dirt and sun so you might end up with a blue live wire on earth then. Then there's monochromatic light, like old sodium lights where you cannot recognize colour, hue or saturation just brightness. There it will save your ass. You have no clue how colour or pigments work mate. All you want is colours that are mildly more convenient in the best possible case.

[@randacnam7321]

@@whatevernamegoeshere3644 In a lot of permanent building wire, ground isn't even insulated so fading can never be a problem. And our blue insulation is often a lot brighter than the blue used in IEC spec cable. The worst issue I've seen in fading is with yellow wire, and that is why 277V/480V uses gray as a neutral. Plus, American practice is to put wires where they can't easily fade. Even where they do, white and black are real easy to distinguish and red is still visibly pink. There are a lot of bright colors out there for wiring insulation, and one of my main greps with the IEC color spec is that they use none of them to contrast with the dark blue. And apply your LPS example to IEC colors: L1, L2 and neutral look identical. Even L3 may be hard to distinguish. The only thing I have no complaint about with IEC colors is the yellow green striped ground, and even then it could be improved as IEC spec says the stripe cannot twist around the cable. It should twist or at least have multiple smaller yellow stripes, as otherwise it can look like just green or just yellow in a bundle or loom.

I opened it an saw that the fuzes were the size of beer cans and a notice said that it was 600v 3 phase. I wanted to determine if it was hot and I didn't have a volt meter on me, so I noticed some wire on the floor. I picked-up a 2 foot or so length of 1/0 ga. insulated and put it across the outer legs to see if I got a spark. This fireball jumped out of the box and covered me with molten Copper.

You do wonder if they would have been best to replace the entire panel for something safe and easier to work on. How much longer life span has that board got left especially considering the amperage going through it?

[@cms4467]

@@residualelectrical Thanks. Wasn’t sure that they would be long enough when I looked at them? Have you found anything for PZ2/3 terminals to use it with? Some of Schneider boards seem to like to use them. Just a thought would it have needed to have been that big? Not a complaint but you have only connected on to a 600amp and the rest of the out going ways are not that big so could you have used a 1000amp or similar? Don’t know if that would have made that much difference? Keep up the videos.!!!

Giving the head shrink pinch at the back once warm does work , again not ideal but can get it looking pretty smart

Nice to see some 'meaty' electrics. Can quite understand that you wouldn't want to be anywhere near those cables when livened up. I would be away standing in the next field!

[@jamescross2229]

Hi from NZ. Great video. That torque wrench was pretty flash, and you mentioned that you`ll download the applied torque values afterwards. Is the torque settings for the 185s into the MCCB pretty critical then? Cheers.

Hi . Heavy duty job there jeez. What is the unit in the corner doing ? our factory has something similar with a breaker switch on the front . If this breaker tripped or someone knocked into it , as it by a door and very low down would it knock out the power to our factory do you think ? What is the purpose of it ? rgds Don

Did you check the two cables that were fastened on to the sports where you found that arc flash on the side of the enclosure.

[@jongurney]

The previous sparked crossed the life out of that thread on the l2 eh. What a squeeler

[@TheSoloAsylum]

I've done everything you did here only with the panel live the entire time, and I can't count how many times I've done it. I actually prefer to work panels live, it's keeps you sharp all the time. Also if my helper ever brought me an aluminum ladder into the electric room with an open panel it would be his last day.

[@idontgiveaship2575]

Here in the Netherlands we have a ladder manufacturer who produces aluminum ladders coated clear, black or gray and they have a special line for electricians, they aren't aluminum but fibreglass. Yellow coloured. Don't know if that is the case in the video.

[@guygfm4243]

I love the work you are doing, had you thought about doing some sort of insulating guards around the in comer so that it would be safe to take the cover off live and utilise the main for future times?

[@chrisnorth3458]

Sometimes unless someone asks for something like that its not worth the risk, someone else might open it up and still get killed and then you get the blame for "modifying" it

[@JasperJanssen]

@@chrisnorth3458 I was thinking that maybe they deliberately don’t have one of those, because you’re not supposed to be working on the main stuff while the incomers are live? Especially given those live incomer terminals are not otherwise boxed in, so if a wrench drops down… The danger in boards like this is probably not so much just touching the live bits - no matter how high that voltage is - but especially arc flash explosions. (Is it just 230V at really high currents? Or is it like 1kV?)

[@BTW...]

@@chrisnorth3458 Blamed for installing protective shrouding around incomer flags and busbars... that brings it up to modern Standards? And you suggest some lawyer would try to blame those that installed proper safety shrouding, rather than blame the dickhead that worked around it to get killed?

[@BTW...]

@@JasperJanssen That SCA was built prior to Standards that had shrouds mandatory. The very real danger is accidental contact to any of the 3 phases, or arc flash by some idiot shorting between phases. It isn't "just 230V" low voltage AC... and the prospective fault current is far higher than 2kA. It isn't High Voltage 1.1kV either. Can't you tell the difference between High and low voltage switchgear?

From US. I’ve never seen electricians use or even have an all aluminum ladder. Safety glasses?

[@sbusweb]

+Residual Current Looks at first from the offset like the incoming 4 live cables (N L1 L2 L3) do not go through the same hole... The ferromagnetic problem/effect comes into play therefore -- in this case if the load on all phases was not perfectly balanced, there would be a net magnetic field around the neutral incomer creating current in the chassis etc... Is there actually a long slot in the metal back there to join the big and small hole for those 4 cables, therefore? I may have seen such nearer the back -- plastic-covered?, wasn't very clear...
