Which conductor colours to use?

If the instructions recommend heat resistant cable then that is what you should use.

The manual also states that the installation should be done in accordance with the relevant regulations.
Does anyone have sight of the part of them that covers heat resistance?
I would be inclined to put forward the hypothesis that standard cable becomes heat resistant cable when appropriately sleeved, but I’d be interested in any other opinion.

Relevant Regulations could cover a multitude of different things which is why it is a minefield for someone who isn't suitably equipped/competent to do this sort of thing. Charity or not it is always advisable to seek a professional to carry out these works.

Thanks for your concern.
That’s not going to happen, although as I say the installation is being completed to a sufficiently high standard to ensure that it can be tested and inspected as safe, by a suitably qualified person.

You will need to ask whoever is testing and certifying it if they are willing to put their name to normal pvc cable with heatproof sleeving.

If there is a circuit board inside the box it's unlikely to be getting particularly hot, although the heat developed in the connection resistance and the normal dissipation of the cable will raise the temperature of an already warm cable. Heat-resistant sleeving will not stop the original insulation deteriorating at high temperature. What can ultimately happen in extreme cases is that the insulation hardens and cracks, leaving the conductor insulated only with the sleeving. The question then is whether that is an adequate replacement for the insulation.
