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?

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)

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 ?

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

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