A beautiful brace of videos about what is arguable the finest cable around. Oozing Health and Safety at its best, MICC tests true craft and divides the corner cutters from the diligent. I love a bit of MICC. My JoiStripper was my Dads and I treasure it.
Back in the day Coventry City Council were one of the biggest users of MICC (according to BICC). We installed miles of it and I worked for one electrician who could straighten it to perfection even when pulled through multiple walls. His preferred method (which the apprentice had to copy) was a stripping bar made from 1/2 handle off a plastic crate, the reason was it produced beautiful, straight, tight coils of copper which were kept in a 'Tatt' box....
I loved my key stripper. And yes I have used my screwdriver before when I could'nt find my key stripper. Good old days. And I have done mains size MICC with it.
I made up a tool a while ago to help grip various cables or small pipes while working them, Basically cut some steel pipe about 3 4 inches long, then slit down the length for 2 halves, and weld into some cheap mole grip jaws so you have a T shaped tool - very useful for gripping micc cables
Ahhhh, the dreaded spam key.....you knew your evening meal easing going to be memorable when you saw that key.....just as stripping MICC with one would be
Learn how to do it with a tommy bar or large flat head screwdriver and a ringing tool,then you can make off any size. With large pyro ,sometimes the pots don't want to go on after ringing,just get a flat file and rub gently on the end of the copper sheath to remove the burr,now the pot will slip on easily.DODDLE. remember practice makes perfect.
I've also used a pair of long nose pliers to remove the copper sheath, if I've forgotten the strippers - bit of a phaff but it's do-able with practice. Also have a good look at the sheath where the pipe cutter / ringing tool has been used to ensure it hasn't been overtightened and pushed the copper sheath onto the conductors - a quick IR test at that point helps.
Brings back memories of my apprenticeship, having competitions between ourselves to see who can strip the most copper with a T bar without snapping the copper
I so remember all these methods , the joystick was always my favourite tool, the blue stripper was a nightmare to get set up right, the spam key method was used when we forgot the the proper tools always remember not to ring the pyro too deeply when using the spam key as it can break away before you have reached it and then your in trouble, don't ask how I know. Not my favourite cable to install specially on really bad uneven brickwork. We didn't have lasers in my day just string lines that didn't always show up on rubbish walls. Installed many miles of this stuff in petrol stations most of it in the underground ducts & unseen.....recently retired now but it brought back a few memories seeing this.
Ah the good old days of pyro young guns don't know how easy they have it Like to have seen your face after you used the key that Def worked better than you expected lol
@@GSHElectrical Oh, so there is no reason for it drawing in moisture, you were just saying to be careful leaving it stripped for too long as to damage it
Why ring the cable before you strip it ive seen the copper shealth snap at that point while stripping. i only ring the cable a couple of inches below the stripping.

Brilliant. Used to love working with MI cable . Don't use it much now .
Luxury man...😁 I was never issued with any form of stripping tool, had to use my side cutters, working around the cable.
So the key technique looks just like the old way of opening the cans of ham, spam etc 🤔 great video
I well remember those keys to open corned beef cans and have the scars to prove it.

We made up a tool to fit in potting tool out of a micc gland so you could put pots on when not needing a gland for entry.

We used to see how many ends you could make off with a stick of compound.

How do you connect a fan extractor to down lights?

Great comment
So why does it draw in moisture? Is there a reason for this?
The magnesium oxide is hygroscopic
@@GSHElectrical Oh, so there is no reason for it drawing in moisture, you were just saying to be careful leaving it stripped for too long as to damage it
Very nice making off on bench ,now try up the top of a ladder in the semi dark .lol.
Thanks for watching and commenting 🦾
O that's more fun. Been there done it. And in a bloody hot ceilings void. 😃
@@stephenlittle7534 I've done the reverse in a room open to the elements (no windows fitted ) mid winter ,what joy as a sparky.
My old boss had all 3 of those strippers in his tool box but always ended up using his T bar couldn’t handle the
Modern rotaries
I've never made off an fp200 end
Piece of piss compared to a pyro end!
