Thoughts on this please, functional earth leads obviously showing signs of heat damage, the greenish coloured neutral leads compared to the blue ones are coloured throughout their length, maybe heat has caused this?

I can’t see evidence on the neutral leads, they are just an odd colour compared to the blue ones we all know and can see in the picture.Can't really see much from the photos, problem wise, mate.
I can't see heat causing the neutral problem and if the funky earth leads have heat damage, it's strange.
If they were damaged through heat the RCBO's would be goosed. Are they operating?.....unless it's heat from another source. They were the usual cream/white, I take it. Are there changes in colour throughout the length?I can’t see evidence on the neutral leads, they are just an odd colour compared to the blue ones we all know and can see in the picture.
The functional earths have suffered discolouration by I’d imagine, heat, them rcbos are warm to the touch.
Ive asked Schneider to see if they had produced such coloured leads , I’ve not heard back as yet, never seen Schneider rcbo neutral leads that colour.
The functional earth fly leads are also sticky to the touch

Are RCBO's overloaded?
Well The DB is located in a cleaners cupboard which houses cleaning products, DB cover is correctly fitted etc.Hi - if the insulation is tacky it’s breaking down rather than burning up, I reckon. Any chance of chemical pollution?
I’m an idiot dryer and I think that this is obvious. They do make battery only units .
Doesn't explain the green neutral or the yellow RCBO earth fly lead? As far as I know all manufactures used white.Variation of colour in line & neutral conductors could equally be the result of two different brands of cable, given that colour is uniform throughout the visible length of each. Try comparing Pitacs with Prysmian and you'll find exactly this sort of variation.
The CPCs also appear to have two distinctly different sheaths.
Indeed it does not and I'd taken those fly lead to be CPCs - couldn't understand why they were single coloured.Doesn't explain the green neutral or the yellow RCBO earth fly lead? As far as I know all manufactures used white.
I have been installing some large air handling units and a chiller over the last week, the chiller control panel has a Schneider MCCB switch as an isolator and various Schneider contactors, none of them look quite correct. Hope they aren't fake too. The unit screams 'made in china' with it's sloppy construction and incoherent labels and instructions.Schneider / Merlin Gerin MCBs have been faked in the past although crudely, they were merely switches with no tripping mechanism. But in my line of work we see fake products that can seem to work well unless pushed hard.
