Shocking I am only 22 and have worked with more Ex d pyro installs than you old timers!

You Best thing to do is have a PIR done and as a landlord you should only worry about Code 1 or 2's.

oh and Pyro doesn't need to have additional protection(RCD)

I doubt that little statement!! lol!! Those older sparks that have worked on MICC, would have worked on far more installs than you have. Ex d or normal, there isn,t a great deal of difference, apart from the gland itself....

As for using wheel straightners on this small size of MICC's .....those cables would have had to of been in a really bad state, for the wheels to work harden the sheath. To be honest i can't remember anyone using those wheel straightners on such small dia cables, they were generally used on the larger cables....

You wouldn't have to be a genius to know how to stick a new metalclad board in there. If you had even just a small amount of experience with pyro you could quite easily terminate the existing glands into a new board. The only problems would come if that was not possible and some stripping and re-potting needed to be done which is doubtful.

Again though, as UNG has already mentioned, how you would be able to tell a chancing Electrical Trainee domestic spark from a domestic spark with some experience of pyro is gonna be a hard thing! Maybe ask them what method they use to strip MICC? Or maybe you could ask them what hygroscopic means? Easy answers to find on google but not so easy to answer when put on the spot! Who knows.

Because its pyro the term that needs to be used is "electrically and mechanically sound" or in other words use a metal fuseboard. and a 19mm cutter if 3/4.

Forgot to add this is a ex council house and the pyros need to get an IR test but me thinks he may need a rewire Why because I have seen this before and have the pyros were down IR wise
plus i dont do rewires

Most if not all electrical trainee boys would run a mile seeing MICC cable..lol!! ...Probably even advise the customer to re-place with T&E....

But this is why i mentioned finding an electrician that has MICC experience in my earlier posts and unfortunately that would exclude most young and new electricians.... Virtually no training in MICC work at all now days in any of the electrical courses at collage!!!

 

[D Skelton]

You are right, most Electrical Trainee's would run a mile however some wouldn't, hence the phrase 'Chancing Electrical Trainee spark' lol.

 

[wade88]

Cant lie, id be running haha

 

[telectrix]

a lot of the younger guys may never encounter micc. that's not to say they are not good electricians because of their lack of experience with it. the red arrows pilots have probably never flown biplanes. that doesn't mean thy're not good pilots! tin hat firmly in place.

 

[D Skelton]

Anyone who did the 2330 in college should be able to confidently work with MICC.

 

[needasparks]

Bet some questions turn up now about pyro in general I bet the codes will be interesting after the test though.

 

[former sparky]

I Spent many years doing micc work and yes there have been cables that were faulty mainly due to poor installation,but this looks like a tidy job at the board so strip the existing DB remove bushes remove DB mark new one and if your feeling so inclined over sleeve the tails to limit the chance of breaking the seal. If the pot and seal has separated,recrimp and test. But hey I'm just a former sparky. 25mm 4 core was the largest I'd used but it was from the basement to the roof of a 6 floor building . Oh and work hardened, bend a piece of 2L1.5 and see how much abuse it takes. Actually while your at it cut off a piece put you insulation resistance tester on it and **** it with a hammer! It is rugged stuff.

 

[panicoll]

again mate your not right with that one glands are all Flameproof EXd just the pots that are different.

I think the general advise would not to let any house bashers even consider the job lol let them stick to crawling about lofts with the glass wool! hehe

I can't work out whether or not you're joking or whether or not you are blatantly looking down your nose at those who house bash? I house bash, among other things, and would be more than able to handle work involving MICC.

Just coz a spark house bashes doesn't automatically mean that they must only be a Electrical Trainee with no experience of MICC. You don't have to be part of some 'elite' club just to have ever handled the stuff! I could teach the missus (with no electrical knowledge whatsoever) in no more than an hour how to handle, strip, pot, gland and terminate MICC! More than enough knowledge to be able to deal with such minor work. The OP's job wouldn't require a spark to have any knowledge of even the middle three of those! Just basic knowledge of how to handle and terminate would be enough.

I'm sure a few will shoot me down for this post but I do hate it when people think it's ok to treat house bashers as the lowest common denominator!

Advanced apologies if you were only joking!

 

[panicoll]

My old journey man was a house basher and he bites every time aswell good to know you can take the banter tho hehe

That's one hell of a statement you must have been installing Pyro while you where still at at school and have developed a method of fitting more hours in to a day
