MICC/PYRO advice please

[PJH2903]

Been to a quote for a job this morning. Customer has just bought the house and wanted me to quote to replace/move an old fuse board as there were 2 in the house.

On looking at the job it appears that the old unit in the kitchen is being fed from the newer unit under the stairs in MICC/Pyro, the install date on the newer board is 2011 so don't know why the original spark did not just replace it at the time.

Told the customer I will need to do a full eicr to see what needs doing in the rest of the property but the old board will need removing (which he understands) and I would need to trace the circuits to see how I can best get them back to the main board.
As there is no labelling on either board I have suggested he plays flick the switch and makes a list of which mcb switches what off to save a bit of time when I return.

I have never had the ‘pleasure’ of working with micc as I only do domestic work so my question is do I need to take any precautions when I rip it all out?

considered it a sub board and you going to up grade it to a metal board to 18th ,you need to find what I is it feeding .and of course is the sub tails to it .
you could use the existing micc ,has long has all test carried out .
just to add looking at the main board some of the mcbs are not marked up .

The outer dome cap is sealing the cable to the gland body. Below it is an olive which compresses to the cable sheath when the dome cap is tightened. Releasing this should free the cable from the gland body, this is not an ideal thing to do once the olive is bedded to the sheath and body but needs must if you are not replacing the gland. You should then be able to free the gland without twisting the cable which you need to avoid at all costs. Some have earth tail pots fitted to the cable for earthing purposes if not I would probably fit an earthing nut, it looks metric from the dome cap which I can see a 2 written on it.
The dome cap will denote the cable size, 2H 2.5 means heavy duty two core, 2.5mm. 2L 2.5 means light duty two core, 2.5mm.

if you are ripping out the micc then no precautions necessary

if you are going to re-use the micc feed then don't cut the gland off otherwise you will be in a right old pickle

How is it currently glanded into the plastic Consumer Unit?

 

[drzsta]

Its Metric 2L2.5 and would be no problem to re-gland.

Edit; although it has no earth tail. i'd be interested like 123 has said how they have terminated it into the plastic CU.

I think we will require a picture so we can see exactly how it was 'correctly' glanded to the new board....

I like the Safety Electrical Connection on the front of the consumer unit.

Not sure why the quotes. It's about the only cable I enjoy installing these days.

But wait, that copper covered stuff at the right hand end of the new board isn't MICC. Or if it is, it's gas MICC.

 

[Dustydazzler]

if only we could see a picture with the lid shut we could inspect the gland

rarely see orange micc in houses these days , see a bit of bare micc on my travels but rarely orange

It's all metal C.U

T'other end is plastic though, and could be amusing. But if it's being axed, or even hammered, not terribly important.
