Burnt Main Downstream Neutral

[Ian1981]

Where was the combustion on the plastic cu?
Loose neutrals and all that

The neutral connection is the sheaving degrading or it is the flash from the camera?

Nice amount of copper from the neutrals on show and the looped back live on the B6 breaker.

Sheaving???

Has the insulation at the top of Neutral gone dry/brittle ,
can see where it's "flowed to blobs" .
RCD end doesn't look as tarnished !
(Nip it up - not completed?)
(or later diagnosis/messing about-RCD-tripping)

Plastic will often lump together due to its molecular make up when exposed to heat. The heat here was insufficient to cause thermal breakdown of the molecules and hence no gas is released which would be required to create ignition.

As an a by, should the owner be told not to use the installation, until rectified?

You been drinking already?

Do a lot of fire risk assessments.

What answer was a proper physics teachers response.
Thank you sir.

Do you get twitching with a box of Swan Vestas in your hand

To cover you behind send the customer a Danger Notice without delay. It looks too far gone to be cured by tightening the screw up. What do you mean by IR is open circuit (OC) ?, if it is how have you got satisfactory r1+r2 ? You have what is known as "guilty knowledge" of a potential fire risk. Ideally tell them it must be isolated and the C.U. replaced immediately, I realise that may not be practical, so send the Danger Notice and make it their problem not yours ! Sorry if I sound like an arse but where there's a blame, there's a claim !! .
