    Have a look at Regulation Group 531.3.5.3 - TT system -  Regulation 531.3.5.3.2.201 on page 156 - its advocates that a PVC/PVC supply tail is deemed to meet the requirements of double or reinforced insulation. 


    Personally I have a;ways ensured that when the supply tails enter a Class 1 Enclosure installed on a TT System that they should enter via a Class 2 gland. However, the above seems to blow this requirement out of the water!
