table 4d2 is still for T+e bs6004 and gives a value of 52A in trunking or am I missing something

am I right or not ????????

but that would mean there no insulation in the property, and most if not all new builds have insulation in them so i can't see how it would b ref method c

Rather than derating it's generally better to avoid the insulation! No reason why in almost all cases you shouldn't be able to prevent it being a factor.

If you have 400mm of 2/2 trunking fitted vertically where it passes through the insulation you really dont need to apply methods related to cable in trunking.... the trunking is open top and several orders larger than the cable so any thermal dissipation restrictions will be neglegible and clipped direct can be used as normal.

Table 4D5 on the 17th (green one) pg 340 is T+E

yes I know that but it does not give ref method B(T+e in trunking)table 4d2 is also T+e but with other ref methods.
Am I not correct
