EICR Coding challenge for trainees.

[MFS Electrical]

Im going to post up a couple of pictures have a good look and see if there is anything you would code during an EICR....
There are no daft answers so give it a go.

I’m after a Code i.e C1,C2,C3, FI and if possible a reg to back it up.

There may be some things which don’t really warrant a code but could be done better feel free to post about these too.

The CU cover has been removed to have a look it is available, has all required labels and all spare ways are blanked off on the cover.

I've just started the 2391 course today so this is really fresh for me.

I'll post my thoughts later or tomorrow

So just had a quick look. I've not really studied the codes but I'll give it a go with my limited knowledge.

First things I notice,

* Too much copper showing on the tails into RCD. C3

* Too much copper on neutrals in neutral bar. C3

* Links between main isolator and RCD too small. C3

* Exposed busbar. C2

* Tails wired into RCD and not main switch. C2

Can't work out if that 1.5mm2 on that 16A is showing signs of overload or it's a shadow? The breaker is too large for 1.5mm2.

Not really sure how to word it but the 2 neutral bars are not going to be acting as a split board of they are both linked together. Is that correct?

Also if that board is not isolated somewhere else it's actually still live (even though it appears to be isolated with the main switch) obviously due to the switched tails.

Good effort Codes can be subjective as long as you can back it up you can code it whatever you feel is right... there are signs of overheating somewhere in that CU but it isn’t on that 1.5mm cable.........

 

[gazdkw82]

I'll try and back it up with some regs.

Can't see any other signs of overheating. It's probably staring me right in the face lol

The neutral bars appear to be solid behind the white plastic but there is a Gap between them.

To be honest the picture isn’t exactly the best. It’s a Final Circuit cable that’s a little crispy but not perhaps, where you’d normally expect.

 

[gazdkw82]

Uumm have they melted away from the housing?

 

[MFS Electrical]

It’s above a 6A MCB very crispy

 

[gazdkw82]

Is it the 1.5 off that B6?

 

[MFS Electrical]

Is it the 1.5 off that B6?

Yep, not where you’d expect it to crisp up though eh? More often than not it’s at the terminations you see heat damage.

This is the top surface of the CU.

As I said not everything can/should be coded. There may be nothing wrong in some pictures as well. Recommendations for how it could have been done better are good too.
Have a go and see what you can spot.

Recommended remedial solutions will get you brownie points as well.....
