Landlords EICR and t&e sub mains without RCD

C3 all the way. No way a C2

C3 all the way. No way a C2

Why..?

 

[Andy78]

Eerr
You can see a socket ....
You can't see a buried cable..
You can screw into the live then lick the screw ... if your that way inclined..
No operation of any protective device..
Is this not the point..?

It's sort of the point, if your point was that you cannot possibly protect against every random eventuality and so coding should be realistic based on normal use of the installation. But I don't think that was your intended point, just what I inferred from that.

Why do we fit RCDs for stuff buried in a wall less than 50mm deep if not to guard against things that aren't "normal use"??

 

[richy3333]

Why..?

Because if I am the inspector I am suitably competent, qualified and experienced enough to judge a T&E ‘sub main’ as was described in the original OP as a C3

For additional protection. Not basic or fault protection.

To me, the “cables in walls” reg came as a safety improvement, but not having it wouldn’t automatically mean the installation was unsafe.

Ok I accept that point of view.
This is why Im Posting this .. because I value the feedback here.
At this time I'm not completely sure i agree completely.
The thing that worries me is just that we have the current regs for a reason .. this goes against them.
I need to be happy with what I'm doing .. so I seek consensus...not just cost cutting for landlords.
I thank you for your points.

For me right now .
Both.
But I'm willing to be persuaded otherwise .. but I'm not yet.

With tt anyhow
With tncs or tns yes its additional... but it's still a requirement really unless someone can show me something that says different.

If you need RCDs for basic protection you are in a whole world of trouble and cables in walls is the least of your worries.

 

[mattg4321]

Do you know that the T&E is buried at a depth of less than 50mm?

Maybe you can see that it is, or maybe you're guessing?

I had a similar situation recently. As far as I could see it looked like the cable was always over 50mm deep in the wall, but I couldn't inspect the whole run.

I didn't code it, but listed it in the limitations. You'd hope that the people who installed it 5 years ago would've done it properly...

It is a requirement. So is brown sleeving on black cables that are live. Does not make it potentially dangerous if it is missing though does it.

Accepted.

Is the buried at less than 50mm rule still apply to cables within the prescribed zones?

Yes sir

Yes in the case of TT then it's different. Like I said my argument is solely for buried twin and earth cables less than 50mm deep.

 

[Wilko]

Just thinking out loud - if the TT was PME’d then at least the sub-main would have fault protection. I did a job recently where SSE had just been through and upgraded the o/h and were able to provide PME.

 

[Charlie_]

Yes sir

10 points to Griffendor!

 

[SparkyAndGeorge]

Would there be much point putting a 100ma RCD upfront of one of these sub mains as it still wouldnt meet the 30ma requirement?
