The Man, The Myth, The Legend! Great content as always.
Hi thanks for watching
Gosh! I remember training on pyro I the seventies when it was all screw. The Forman turned up and produced the largest adjustable spanner I have ever seen and slammed it down the pyro onto the fitting which vanished across the workshop. ‘Now do it again’ was the command! The second one held. He smiled and said I could go offshore then. I did it only until about 1978 and never went near it again.
You used to have an insurance reduction if your house or premises were wired in it. A chap who worked at a factory learned this and smuggled it out, premeasured, wrapped around his body. One day he fell off his bike near security and it took two mates to pick him up and put him back on his bike! Thought it might make some of you smile!
Nice to see you back. Hope you are well.
I used to do a fair bit of Pyro in my apprentice days working on English heritage properties - would love to get involved in some more again to sharpen my skills!
Great to have you back Delroy. Proper real life sparking videos.
Thanks watching
Last Pyro job I did was in a new hospital, I did a whole x-ray dept made the ends off tested it all got the polarity marked then moved onto the next area. Only to come back to final fix so checked polarity on everything and all of it was down to earth, after an investigation turned out the manufacturer had a bad batch of pots go figure. Plasterer was happy with the extra work, as was my boss eventually when he didn't have to pay for the fix. Loved doing pyro though proper job.
Oh wow never heard any thing like that, Pyro can be problematic if not installed properly. Your case is unique thanks for watching.
Good to have you back Del Roy 👍👍
Great to have you back, missed your great videos.
Good to see you back!
Great to see your back Del 🎉 I used to love working with pyro back in the day
A great job well done Delboy
Hi thanks for watching, some sparkys did like working with Pyro back in the days
Great to see you back Del! Thanks for the vid
Great to see you back Del!
Did miss your videos, glad you’re back!
Good to see you back. Like watching your videos.
Nice to see you back del, you made the job look to easy with your skill and patience. I used to do a lot of pyro work in the early 90's and still have a load of pyro tools made by bicc (British insulated calenders cables) we where taught how to do pyro at college which sadly isn't taught now to these young sparks. Great video and looking forward to more of them
Thanks Rob more videos in the pipe line.
@@eastwayelectrical Pyro is still taught in College, atleast it was for me
@@BGAVINB yea, its still taught, you do it once, then never again usually
I love the way you fix the cable!
I Like the way Del had to get up on the steps while potting the pot on the Gland to get some extra Torque ..lol..MI you either love it or hate it but its an Art working with it...When FP200 came on the scene it was a Golden as you just needed a Tail Cutter tool and so easy to work with ..Bless
Hi Del. Really missed your content, glad to see you back. 👍
Great to see you back Delroy, you have been missed!! That guy was decent to be fair, very helpful 👍
Good to see you mate !!
Great to have you back Delroy!
Good to see you back del 👍
That guy kept saying. Yeah yeah yeah. Drove me crazy. Keep up the good work delroy.
Nice to see some heavy duty Pyro work - Earlier this year I had a job wiring a fire alarm in a listed building - pulled in just short of 500 lm's of 2L1.5 over three floors, around 100 terminations all told - love working (quickly lol) with the stuff 😁. Made sure to get some time in on it with all the apprentices so they could get experience of a rarely used wiring system - hope it comes in for them in later years.
Great to see you back Delroy
He is back good job.
Fantastic to see you back, Really enjoyed this video. Old skills taught by Old boss's to nowadays Old apprentices, Lol glad I was taught this skill too,
Tricky stuff that MI . Have not touched any in a while.
Done loads in my time once learned never forgotten 👍👍👍
Well and truly SORTED by Delroy . The man of copper and compound .
🤣
Great electrician you are
Keep up the good work 👍
Used to megger the pyro at every stage. When it was pulled in and straightened out, when it was bent round, when the ends where cut and peeled back and 0f course after it was potted up.... what a bloody pain !!
Long time we did not see your videos.. nice to see you back
PYRO - LOVE the stuff ! I honestly could spend hours doing Pyro. Once did a Grade 1 listed building completely in Pyro, everything was done in it, days on end say in a loft with huge adaptable boxes terminating and connecting them up.
Wow that brought back some memories...!
I did my apprenticeship in the late 70‘s. Loved using Pyro though. You definitely need to check your pot after it is screwed on both visually and with a Megger. This is because the chance of a hair of copper or brass being produced when the brass pot is screwed on to the copper sheath. This happened to me a few times. If you don’t take care you’ll short the 2 cores out and you’ll have to do it all again. It can be messy. Left the UK in 81 and have worked abroad ever since. Great videos keep them coming.
Del, you have been missed, welcome back 👍
Just glad to see your heathy n still making videos its been a while🤗
He is back I was driving to a holiday location and heard a beep on my phone and saw a new video I was so happy
Good to see you back Delroy. I really think most non-Electricians underestimate the skills involved and the continued learning to keep up with new Regs. As someone with no training in the trade, I'm sorry the general public don't see more like this to appreciate our Trades people. The maths involved, apart from the physical skill. We should have more respect for people who build and keep our homes and buildings safe, whatever their trade.👍
Well said bridget fidget
Welcome back!
Brilliant jon as allways dell
I've still got a Pyro crimper somewhere, it must be nearly 40 years old now. I used to quite like doing Pyro.
Good Job.
Our flats were built in the 60s and are wired with pyro… it's always fun when an 'electrician' comes to do any work from the council and gets confused because they claim to have 'never seen that before'. I know I'd do a better job myself most of the time. I did loads of pyro work in the 90s, it was an art to do terminations and stay clean! 😁
Good to see Delroy back
Good to see you Del, gave my MICC tools away to some whipper snapper.
The 👑 is back
Delroy …... 5 months missing 😮 I hope you have a doctors note for your absence let this be you first written warning 😊.... as always good video delroy keep them coming
I spent 3 years going all over uk for a big store chain terminating pyro as thick as your arm …. Loved it
Keep up the good videos …. Nice job Delroy
Welcome back Delroy
welcome back del
Always test the continuity before stuffing the compound into the pot then test again once the compound is in then test again when you crimp the cap to the pot I have seen a pot blow and take a lump of a marble wall out.
Good advice thanks for watching.
Anyone trained in the 80’scan do that work You can hit that with a hammer to dress it 😂😂😂
You mean Test the insulation resistance
@@charliemcconville5756 - Nope, you test the Pyro out once you screw the pot on visually and then with the Megger as you could/can end up with copper/brass swarf in the pot, not much fun in having to take a sealed pot off.
Pyro is what I like best, not sure if the outside lights on the VA Museum Exhibition Road side are still using the Pyro that I installed made off in the winter and snow back in 1984.
Also I used a wind up Megger, lots of fun with naive apprentices when you asked them to hold the bare ends...........
@@undercoverdivers - Remember at Uxbridge Tech learning about Pyro, lamp at the end all powered up and the instructor hammering the shit out of it crushing the cable, was amazing stuff as it was still working as it was be crushed.
I absolutely loved working with pyro used to do a lot of it in Acotland and when I worked down in London. The last gland I done was offshore but no one told me that the new pots you needed to stick the neoprene under the pot it didn’t have the little spouts that stuck out like cows udders lol 😂
Wicked video 🎉
Did loads of Pyro/Miccs back in the 70's and throughout the 80s from 1mm up to max 16mm, was a pig to do when it was freezing cold. Emergency lighting etc in Nightclubs and still got all the tools in the garage.
hes back !
I've forgotten how much mineral cable I did back in the early 80s tons and tons of it....I can also remember when FP200 and 400 gold came along thought that was the end of Pyro ....no such luck, it was a bit like marmite you either loved or hated it depending on who spect a Job, personally I loved it. I recently found a load of old hickey bars pyrotenax cable formers while clearing a load of old tools out 😃
Used to use pyro on fire alarms, outside lights and pub toilet hand dryers in the 80’s.
Loved working on pyro .worked on marks and spencer 90% pyro work .the switch rooms looked fantastic with pyro work of art.plus try making off a 7L 1.5
oh yes done many of them in my time Vince in my early days for repeater panel's lot's of inter link's were need in high risk area's of fire next to very hot surface's in some aluminium factory next to the furnace's now shut down due to they moved oversea's the whole factory was piro
7 Core Pyro was my forte the supplied stripping tools where useless so made my own and sold the others off, still have the tool that I made as well well as the ringing, potting and crimper tools, I also have my 20, 25mm conduit threaders no need for a 32mm but would love to have a Hilmor conduit bender.........
4x4 galvanised box should have been used originally.
av still got all my big conduit & piro tool in the attic all still in working order but now a days i don't think it will ever be used again when i am six foot under there is an Aladdin's cave up there some one is going to think what the hell are these for well it will be my son who get's them he's on my will to get the house
love watching you from the states the closest thing to pyro we have is our explosion proof conduiet and fittings we use a liqiud gel to seal the joints with at the fittings
MICC is used all over the USA, most commonly for fire alarm systems.
@@thebigmacd interesting i live in the northeast and never seen it. i havent done much commercial either so maybe thts why ?
I would have tested before filling just in case there wasn't a sliver of brass shorting it out, also we always used 1000 volt megger back in the day
I used to do work in a large house totally rebuilt in 1986. The whole house was rewired in metal conduit and Pyro
Started as an apprentice in 1964 and worked with MICC for many years
It used to be good watching the older sparkys working on Pyro. thanks for watching
what other cables did you work with when you first started? was it pvc or the old rubber stuff?
Hi Brother Delroy, how are you doing today? I am an electrician in Charleston,South Carolina. I started electrical work in 1978 in Trinidad in the West Indies. The Phyro 16mm is 60 ampere. I still remember the metric system. 1.5 mm is 15 ampere, and 2.5mm 20 ampere, and 4mm 30 ampere.
I've been watching expert electrics videos because I had a very incompetent man ( I refuse to call him an electrician) come last week and the mistakes he made are still boggling my brain. He actually started work on kitchen plug sockets without switching off the main power first. And he left gaps around the sockets and tiles. Shocking!! 😲
Spiders need somewhere to live too.
I remember in the 70s when they replaced the screw on pots with the type that was held in place with a wedge. Special tool was required and they used to come off with a bit of a pull, load of rubbish.
I used to fail on over tightening so the ohms would be lower between L - N. It was a nightmare lol.
Takes me back to the late70s. Today lots of sparks do not use pyro , or have never used it … I am enjoying my retirement now ( since august )… but del nice to see you keeping the flag flying …
Thanks for watching and you comments.
Love micc work ,you can't rush it, to do it well you need some skill too it,.
It has a long install life too
Nice video Del, why did you not run meter tails into the adaptable box. Single insulated cable come to mind, or does the additional sleeving on the Pyro constitute double insulation?
I took sleeving off some meter tails I had on the van and put it over the Neoprene. That made it double insulation in my mind improvisation hope that's ok 😁.
Glad you're back Delroy, I'm sure I remember the old sparkies using glass beads and heat on pyro , or was that my imagination..
you can dry the end out if the atmosphere is damp
also NEVER blow in the pot to clear it you add moisture that affects it
It was not uncommon in the old days to find a pot had been incorrectly fitted and damp in the cable had caused a problem in later years. Normally the problem pot was on outside wiring. We used to take the pot off and slowly run a blow lamp over the cable to get the damp out. Damp will only travel back from the pot 12 inch max
Thanks for watching never heard of the glass bead thing.
@@firsteerr aye take the pot off heat it with a blow torch ON LOW HEAT FROM CABLE TOWARD'S THE END QUICKLY as NOT SO YOU BURN IT and keep testing as you do so till the fault has gone many of them i have done
Wondered where your videos had gone!
it is good practice to carry the fuse, however, there is a bank of about 15 of the same fuse carriers there
i never use a lockout kit , i just disconnect the circuit at the fuseboard to stop any chance of it being turned on/lock broken
You should have put the button on first especially if it's a multiform micc so you know the cables are straight or use your pliers to straighten them and check carefully there are no minute shards of copper shorting the cores push the button as close as possible then put the sealant in from one side to push the air out,always put excess of sealant so when you squeeze it with the appropriate tool the excess can be wiped away and you will know that there is no air left in the pot.
Hello Mr Del... great content..whats the name and title of the music near the end...Cheers
I've only worked with Pyro once, in 1986 when I was learning my trade at college, never been on a job with yet in 36 years - I don't have the gear for dealing with it but can remember the procedure still for termination all these years later!
I've used pyro 3 times in 27 years
i installed "pyro" solidly for five years from 1986 to 1991 when i eft the firm
Beware of getting a shock of of the 'charged ' cable after insulation test. We short the cores to the sheath. Also, did the shroud cover the bare cable sheath? Not too important on an interior cable though.
Is that a bit of K Pop in the fast forward bit @ 17:16? Nice 😎😎
Hey Del, Question about the music in the video.. who's it by? Sounded a little like Katy B.
I've waited so long Delroy! Thought ypu had quit
Where the hell have you been?
I missed you.🤩
@ChannelMakers001 what is it?🤩🤩😘😘
What size conductors is the pyro? What size conductors feed the entire building?
Great fun potting a 19 core pyro😅
Can you post link for that bahco set please ? Or if anyone in comments knows it ??
Easy I think i could remake that off with my side cutters using the old pots and some grips
oh might need a new olive and some new putty, then again new pots and seals would make life much easier and more reliable
Where is the meter though?
Residential wiring in the UK is quite different than the U.S.
Needs a "yeah" counter
Used to gland off 30 ends an hour no downers now they are plastic sparks
USA electrician here. That looks so awkward to me. Bet you seeing ours is similar.
Why did you not upgrade fuseboard to a metal one as recommended now, the the pyro could be terminated direct to it and cables to main switch also gets a good earth via gland on metal case
Hi why would delroy go for that expense ……video is only to move pyro and reconnect temp builders supply (not for regs) also bad idea to leave out main isolator before board (no local isolation possible then)
Delroy is a master of his trade 👍
Delroy …… 5 months missing I hope you have a doctors note for your absence 😃 let this be you first written warning 😂 ….. as always good video delroy keep them coming
I spent 3 years going all over uk for a mayor store company putting pyro ends on pyro as thick as your arm …. Loved it
Good to see you again
It is metal. But it's a temporary board anyway.
Personally i would have just put a metal cu in. Love pyro i grew up on it.
👌
That guy could not do enough to help you and make the job as easy as possible. Don't get many of them.
Rather you than me bud that looks way tricky I've never used it only fp200 thankfully think pyro is a dying art 👏
Surely you shouldn’t be leaving single insulated tails from the box to the main switch??
They're sleeved
Has Delroy been on Holiday for the last 5 months?
Wot os that opening track???? Old rockers or dub......east central caribbean....waitikubuli aka roseau dominica.....
Are original from england or caribbean
I cut my teeth terminating pyro as an apprentice over 30 years ago. Good times.
Why no video for so long?
Proving dead using an MFT on IR WTF
