In this video we look at MICC (mineral insulated copper clad) cable and it associated equipment and glands like - the joy stripper, rotary stripper, key stripper, glands, pots, seals, different conductor sizes and cable sheath colours. It is important to master the skills required to strip MI cable as it is a required of City and Guilds and EAL Electrical qualifications. This video I given an overview on MICC mineral insulated copper clad cable sometimes call MI cable or Pyro cable. This video Is all a out MICC cable and will help support my other videos in this series as well as multi choice exams you may have to take whilst training to be an electrician.

When i learnt stripping MI in the 80's we used a flat bladed long screwdriver, once you peeled enough with some cutters then you could squeeze it onto the screwdriver blade and wind off the outer sheath..

Later years there's been a high amount of pots that have a slither of brass come away from the internal thread and short out the conductors. Always check with a flashlight down inside the pot.

Memories.... flooding back over fifty years ago installing pyros on petroleum refinerys and flour mills. Pyro sizes today 150 H four core, fork stripper, reversing pots to start the threads on to the pyro, blow torch to dry out the cores. Straightening rollers, rubber headed hammers, leather bound benders to right angle or set in to intrinsically boxes, spreader boxes, distboard or LV panels. The insulation tester in a wooden box with a turning handle to generate the test voltage to check pots all clear. The job satisfaction the dressing of up to forty six pyros of various sizes using the mention tools. Always winter on a freezing day wearing a donkey jacket to keep warm. Great video.

Cool Stuff , thanks for sharing Just wondered though Some of the ones you had on display With black sleeving had a little description. Perhaps stating the conductor size etc . So can you get sleeving which states all the information on it ?? As the one you had in the bag just seem to be plain black ?? Thanks again

Hi I found this very interesting as I am not a electrician but have a very keen interest in electrical installation I remember when i was the age about 5 I saw some electricians installing micc orange cable for a fire alarm system in my school this about 1979 I remember watching them installing the installation for days I found it Very interesting from a young age I didn't realize they still use orange micc cable I thought it was just red and white sheathed micc cable find your channel very interesting

Don't forget AlCuMICC, wedge pots, Mole Grip wedge setter and crimper, heat shrink pots, drying out damp pyro,with the friction generated by a loop of string around the cable. Pyro,stripper that used the gland as the guide ( total crap ). Keeping the compound in your pocket in winter to soften it. Round head brass or Black Japaned screws. At the age of 14 spending all the summer holidays 1970 making off pyro,ends on site as my father owned the contracting company...the first 500 are the worst

Out of ALL of these videos about MICC here on KZfaq, and I STILL can't find a single one that explains to me the history of MICC, or why it exists.. what it was (is) used for.. etc. What I HAVE been able to piece together is that.. I get that it's an electrical cabling system, that seems to be a) somewhat outdated, b) primarily used more in the UK and quite possibly other European countries than it is (if at ALL?) in America, and I say this because I'm in my 40's, I'm fairly knowledgeable about construction and know a LITTLE bit about electrical (way more than the average homeowner for sure) and I don't believe I've EVER encountered MICC in the US, even on OLD construction. And I've seen buildings where Knob and Tube was still in use! ..but, what I still don't understand is.. was this just a popular method that was used back in the day? Was it an electrical code requirement or something? Or was it more so just because it existed, was an acceptable method, and it worked really well for what they had at the time? What confuses me about it's existence is.. from what I know about the history of England/Europe in general, is that they spent the first half of last century dealing with two major wars, both of which ended up putting a huge toll on the UK's availability of both valuable resources (such as COPPER) as well as skilled tradesmen! Two things that are essential to the proper use of MICC as a means for power distribution! So it baffles me that this would have been such a popular method for running power throughout the UK'S building's, farms, and homes! So how did it become such a ubiquitous thing when copper was a priceless commodity throughout the war years.. they were constantly building and RE building.. and it's a fiddly process that in order to be done correctly, it requires men (at the time) with a fair bit of skill, dexterity, and knowledge.. most of whom were off fighting in the war? I'd love to see one of those awesome Timeline or BBC style documentary/Education programs, that is all about the history of MICC. Maybe it's just because I'm a total nerd, but I would TOTALLY watch that program! (Or KZfaq video! Wink wink! 😉)

This cable was (and sometimes still is) used mostly for fire alarm systems, or in chemical factories, nuclear reactors, etc and sometimes as the feed for flats in high rises. It existed before we had the modern alternative, known as FP cable (like FP200 from Prysmian/Pirelli) and hence was the only choice at that time for what it was used for, the price didn't matter as much. It is radiation proof, very hard wearing and would need to pretty much hit the melting point of copper before it goes out in a fire. There's still use cases for it though, but less so than before since it's much more expensive than the modern alternatives. You wouldn't really see it outside of those special cases though, certainly not running a lighting circuit within someone's home, if at all seen within the majority of non high rise domestic dwellings.

I haven’t potted in years last time I did was really n a airport in a jet fuel pumping station started of with three meters was left to one meter micc had a. Deterioration b. I mucked up two pots and seals 🤦🏼‍♂️ resulting in the need for a 75x75 galvanise box through crimps continued in fp200 lol 😂

I mean I like this better than USA bx cable.... But I've only found out about this an hour ago ... So I'm intrigued.... The conductors ie; the wires inside of the copper jacket.... They appear to be bear? I'm at a loss as to what your neutral line is? Or does it rely on the earth as the neutral... I don't know how your grid works lol

In 2 core as shown the line and neutral are imbedded within a magnesium oxide insulator the outer copper is the CPC (earth). Thanks Gaz 👍🏻

I see everyone carries an ohmmeter with them for these installs... I watched a video on the fire resistance of these and I'm impressed... Not even bx or a metal conduit is really going to provide that level of protection from a short... But I guess my concern is around what seems to pop up in videos online, improper installs moisture creeping in... For safety I guess you could gfci the breaker... But if the line is critical for emergency lighting exct under those scenarios you wouldn't want it gfci because it would trip and be useless.... Take away, proper install shouldn't have any issue. But most people seem to be doing the opposite of that. I guess my only outside user error concern is how do you prevent an air gap in the magnesium during manufacturing... Is that ever an issue? How is the spacing of the internal lines consistent? All of the lines seem to be bear copper. Basically I'm concerned about internal shorts. Obviously you test all the lines before hooking to the mains... But if someone were to bend of pinch a wire wouldn't that short the system
