What cable type is this? SWA?

[Leesparkykent]

I’ll hold my hands up, I’ve never touched the stuff since college about 15 years ago.

I don't touch it often....I can only count 12 ends I've made off in the last 3 years. 6 on new fire alarm panel that had to be moved up and 6 on 3 switch drops where I ran bare 2L1.5 along exposed beams. The real fun starts when you have imperial cable and metric glands

Maybe I can get away with new sheath and tidying it up then encapsulate in a junction box...

Apparently "we" now call it MIMS I was told I was wrong by the apprentice for calling it "Pyro" or "MICC"

Davesparks clarified this one for me a while back.

MIMS Mineral insulated metal sheathed .... can be any metal sheath including copper.
MICC Mineral insulated copper clad .... just what it says
PYRO Pyrotenax ... brand name
MI Mineral insulated ... all encompassing term

So MI, MICC, or MIMS are all correct for copper clad MI cable

Tools are a bit pricey as well

I still have them in waiting. No idea who had away with my conduit stocks and dies though.

MICC, Pyro Proper cable used to be installed by Proper Electricians

I hadn't until a few months ago but had to make one off for an existing circuit ,made a change to do something different.

If done carefully some of the larger MICC ends can be made off with normal day today tools as an emergency option, mind you I wouldn't want to do many ends without the proper tooling, tin hat on, and I'm in me bunker.

I think you could but only those who have made off a lot of glands would be confident in doing so.

If the time clock is easy to shift down that is an hours work for a competent electrician.

I've heard of the pliers method but never tried it. When learning the skill in college all the tools were knackered and I found the slotted T-bar the best tool for stripping.

The timer is now no longer required as all the spotlights have dusk sensors. It's also extremely old.

You can successfully strip the sheath with side cutters once you gain the knack but it still has to be 'ringed' properly for the pot to fit nicely.

Well you can lose the time clock if you are not concerned about them being on all night and gland the cable at a steel adaptable box.

We did some tower blocks about 13/14 years ago. All communal lighting, full fire alarm system installed in communal and flats, communal power (cleaners sockets, tv amp, door entry) all done in MICC......we worked it out one day that there was over 3000 "ends" to make off! I remember sitting for weeks making off pyro ends on pre cut lengths, the legs of my overalls were white!

It seems to me that without the gland and presuming the other end has been butchered the same,you need to make that end off properly and gland it into an enclosure,or at least don't leave it live,that sheath needs earthing

I like how every fuse in the DB is different.

The sheath is earthed assuming that pot which looks like it has an earth tail is a pot with an earth tail.

I have known electricians in years gone by when using the unsheathed MICC after installing to have to polish it (well that's what they told me )!!.

I was wondering what a polish electrician was. Thanks.

That's the 2nd time I've spelt that wrong.

 

[Devonchris]

I think you need to
Polish up your spelling.

You don't want to see the rest of it! The extension (another fuse board) is quite odd. The end MCB is the power for two fuses in the other fuse board.
