EICR Coding challenge for trainees.

My comments in red:

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- what is the issue here with all covers on?

* Too much copper on neutrals in neutral bar. C3 - what is the issue here with all covers on?

* Links between main isolator and RCD too small. C3 - would it matter what size they are? Also assuming they are too small what would be the danger?

* Exposed busbar. C2 - what is the issue here with all covers on?

* Tails wired into RCD and not main switch. C2 - Agree - good spot.

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.

Sorry for delay.

My answers.

* Possible short circuit.

* Possible short circuit.

* Csa would be based on the installation main cut out fuse. Similar to how you'd size tails. Too small and the conductors would be subject to overload.

* possible short circuit. The real danger would be if there was a missing Blanc or the cover was off for testing etc.

There is a requirement for CUs/DBs to have intermediate barriers even with the cover off any ideas what the requirements are.....

 

[gazdkw82]

This is the top surface of the CU.

Doesn't comply with IP rating of horizontal top surface. IP4X.

IP2X?

 

[MFS Electrical]

IP2X?

That’s right well done.
That the 2391 course that let you in on that one

I not long ago completed the 2391-52 myself and can still remember IP2xintermediate barrier IP4x trunking it was mentioned every. Single. Day. On that course

 

[MFS Electrical]

Any ideas on any of the other pics?

A small amount of exposed copper on the neutral conductors, is not really a problem when you consider the neutral bar is it’self exposed.

True, but this is the prime example of where it could be done better..... The time taken to do it neatly is minuscule and it shows that you take pride in the quality of your work.

Yes, I don’t like exposed copper, even though I know it doesn’t make any odds.
Then again, I always tighten up any unused screws on the busbars, just in case they work loose and fall into an MCB.

My comments in red:

@gazdkw82 really think about why your coding them could it be that it could just be a comment on the EICR with no coding would suffice?
If you can back up your codings with Regs and feel it necessary to code then go for it. A handy tip when coding an EICR is to look at the inspection schedule on the IET model form the list is by no means exhaustive but it can give you a step to a hint for some of the more common situations you may come across.

You need a winner badge for that alone. Last week I went to a property where A.N. Other “electrician” had plied their wares. Customer was complaining of a fishy smell coming from the CU nothing was tight looks like everything was terminated with fingertips not even the screws of occupied terminals were tight nevermind the unused ones. Anyway long story short the Main nuetral was arcing and Crispy as it wasn’t ever tight the sheathing and insulation had almost completely melted off inside the CU unfortunately though I ain’t got pics as I’d dropped my phone in a bloody puddle the day before

And looking for the reg numbers gets you used to the book , it brings you back to similar regs in subsequent searches. Also it helps with relationships with the other section.

Picture 1
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.

As soon as I saw Wylex I slapped a C1 on it

 

[richy3333]

1. Potential live accessible parts (assuming CU is live!). Depending upon location C1 or C2. Looks high to ceiling (don't know ceiling height) but probably a C2. C1 if low and easier access.

2. Lack of labelling either a C3 or just a comment (I normally use the phrase 'bag o rubbish' in the comments section ). I see circuits not labelled, no RCD label, no next inspection date label etc etc so I'd probably C3 it.

3. Mixed manufacturers parts. Can't work out the name on the RCD. (per IET and BEAMA guidelines) I'd C3 it. Apart from laziness/couldn't give a rubbish I dont know why the contractor didn't fit a Crabtree part?=
