Exposed T and E's during test.

MKSparky · Apr 23, 2019

Hi, I am new to this forum and can't find an exact match to my search.
I am new to testing and inspection and have come across a db mounted in a garage on the wall whereby the t and e's for all circuits are clipped direct to the wall before entering the ceiling approx 1m above.
Is this deemed as a C2 or C3 on test cert?

Thanks.

What is wrong with having cables clipped to a wall?

Dustydazzler · Apr 23, 2019

When did twin and earth clipped become a code violation

Andy78 · Apr 23, 2019

The cable's sheath is sufficient to protect the basic insulation. What's the issue you perceive and which regulations do you think this is against ?

Spoon · Apr 23, 2019

Its even mentioned in Table 4D5, Reference Method C. (Clipped Direct)

Stspark · Apr 23, 2019

OP, what code do you think it is and why?
Genuinely interested, what qualifications and experience do you have?

Spoon · Apr 23, 2019

Oh, and welcome to the forum mate.

MKSparky · Apr 23, 2019

Thanks all. My thinking is with reference to the condition report section 4.16 where the cables are not mechanically protected.

I have to ask, what’s your electrical experience and qualifications?

What do the regulations referenced in section 4.16 have to say about the example of wiring you are inspecting ?

Nigel · Apr 23, 2019

The outer sheath is classed as mechanical protection. The environment the cables are installed in will dictate if it is sufficient mechanical protection. For example T&E clipped on a wall at high level with nothing around it would not warrant any code. T&E clipped just above a shelf used for heavy items may warrant a C2/3.

Hi Andy. Thanks for your help on this. Really appreciated. I have re-read the sections in the regs and they refer to mechanical strain, not mechanical protection as I had read it earlier too hastily.

Thank you. I perceived the regs incorrectly.

A code maybe deemed necessary if the top of the consumer units IP rating (IP4X) is compromised where the cables enter the enclosure

telectrix · Apr 24, 2019

might not warrant a code, unfortunately there isn't a code for an eyesore. it's R.A.F. ( Rough As F*CK)

Charlie_ · Apr 24, 2019

Do any of the other circuits need RCD protection?
What’s on the utility circuit?

Taylortwocities · Apr 24, 2019

All of the circuits on the right are not RCD-protected. Some, maybe all of them, may deserve a C3, or C2. It depends.

Dustydazzler · Apr 24, 2019

On an older existing installs I am not overly fussed about clipped direct so long as it shows no evidence of damage.
I have clipped twin and earth in my garage from new been there for 30+ years and absolutely fine with this.
Same with older installs with non rcd on the lighting I am not overly concerned.
I have non rcd lighting.

Now if in the OP the cable sheathing was all chaffed and bashed up I would suggest so over capping

Oh I dint know...

I quite like the abstract artistry of the wonky cables and mixed colour pallet

They are mechanically protected.

Dustydazzler · Apr 24, 2019

In the U.K. the outer pvc sheath is considered mechanical protection on twin and earth

Now in America and Canada the outer jacket is not classed as mechanical protection and if run on wall should be either in flexicon or ridged con-do-it or boxed in

Dustydazzler · Apr 24, 2019

Back to the OP a very quick and cheap way to get round this is to screw 2 bits of old wood to the wall and box the cables in

MJPD29 · Apr 24, 2019

No code for those cables

Have you done the actual course in testing???
Because if you had you would know .
According to your question you don' t seem to know what these codes mean.

Charlie_ · Apr 27, 2019

You should purchase one of the coding books from the scheme that you are registered with..
In that way you will be educating yourself and coding in accordance with the ones you are affiliated with
