    Correct size trunking for heat dissipation?

    I have to do an install using trunking which I have nebr used before, I understand there had to be 45% free space inside for heat travel. so what size trunking do I need to fit two 2.5 t&e cables inside? As I said I have never used trunking before so it is new to me.
