LIM N/V FI codes?

[ppelec100]

Hi just a quick one, I know some might say it’s pretty self explanatory but I want to get a few ideas.

What are the differences with the eicr codes and when would one be more suitable than the other.

I know c1 is immediate danger things like gaping hole in consumer units where you can reach the busbar, live terminal if socket busted open and you can touch it..
C2 is if it would be a danger if a fault occurred like no cpc to class 1 fittings
C3 recommended improvement like labels not on CU or no Rcd if install is older than when it was a reg

what about when it comes to LIM and N/V? Say for cables concealed in walls/ceilings or things you can’t see or access etc would you be more inclined to put LIM because you’re limited to access etc or N/V because it wasn’t able to be verified? I’m going to guess LIM because you verified some but limited to how much you could inspect? Do you note down for every single LIM code that you couldn’t access? Because I can see there being a lot of notes because of this

Also FI… this is only used when you have no access to the rest of that circuit which seems to be problematic right? Like if theres no end to end continuity on a ring and part of the ring is in a locked room

Because you can't see it, so N/V.

Okay thank you. So in what different scenarios would LIM supersede N/V? I’m a bit cautious of which one to put over the over to cover myself and get it right.

I’m going to say LIM when you can’t test something because of limited access such as not being able to get into a room or can’t move furniture out of the way and also if you can’t remove an accessory as it will damage the finishing or fabric of the building? Any other reasons you can suggest?

When an electrician encounters a situation where they cannot properly test a circuit or component due to limitations in access or other factors, they will mark it as "N/V" (Not Verified) and note "LIM" (Limitation) on the report to explain why the full inspection couldn't be done.

When you say mark it N/V and note LIM do you mean N/V on the schedule of test results boxes and LIM on the inspection schedules sheets?

Also, for 5.17 on the inspection schedules sheet, I did a sample the sockets and most connections were alright there were a few that had loose connections and the conductors popped straight out when I took the face plate off.
Now I’m a little bit stuck on what to code this, because I’ve fixed it it would be no code but I’m inclined to put c2 for before I reterminated. I don’t feel comfortable ticking it as there will most likely be more shody connections but I might be there all day taking off faceplates when it’s a report not fault find…? Where do you draw the line?

Napit book about coding is worth getting.

The Principal behind say 50% sampling of sockets on a circuit is the assumption that if you don't find any faults, the rest should be ok as they were installed at the same time to the same standard.

in an ideal world, the next time you did it, you would sample the other 50%
however, in my opinion if you find a fault with any one socket on the circuit, you should then check ALL the others for a similar fault.
after all, you cant say that all the ones you checked were fine therefore the rest are likely to be ok.
if you check 10 out of 20 and find 2 faults, then it is statistically likely that there are 2 faults hiding in the ones you have not checked.
