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!
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.
hi del think i have done this right av not sent messages before but here go's wouldn't have a clue what piro was nowadays it's too much like hard work for them ? it would have to be self pealing stuff or they have some sort of battery operated stripper and potting tool for them to be able to do it every thing now is battery powered tool's call me an old fart in my early fifties but i don't care
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
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
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 😁.
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.
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.
@@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.
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 !!
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!
Too many people fear pyro because of lack of knowledge and some have never had experience of terminating it.. Its not a difficult cable to terminate... its just a bit more harder to install or move.. just be mindfull of your bending radius as in not kinking or pinching, twisting etc... take your time in stripping it, testing it, potting it, and closing it up... just remember to put your shroud and gland on before hand... insulation test it as you go and then bell it out at end for finding the line and neutral... enjoy the satisfaction when youve done it..😊
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! 😁
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
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.👍
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
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.
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
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
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 …
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.
You are acting like you have never worked with micc cable,I was one of the first electricians to work with albumin cable which is the aluminium version of micc it was soon after ceased to be because when bent it cracked,you would megger it and it would be clear and 24 hrs later rest it again and it would be down,I've made off micc cable for a main supply under the floor of a school with huge rats 20 feet away staring at me so yours was easy,but sometimes you would get a bad batch of pots and whatever you tried the pot would just not thread onto the cable,we had an apprentice that spent 2 years of his apprentiship working with micc working on a huge theatre
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
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 😃
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.
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.
Wot os that opening track???? Old rockers or dub......east central caribbean....waitikubuli aka roseau dominica..... Are original from england or caribbean
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.
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.
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
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,
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.
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 😂
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!! 😲
