Jan 28, 2011 · One thing I've never understood is why, although Table 4D2A gives CCC figures for "two core cable (70 degree PVC), with or without a protective conductor" (and says nothing which excludes 'flat cables'), some of the figures for Reference Methods A and C are very slightly different from those given in Table 4D5 ("flat cable {70 degree PVC} with ...

Feb 11, 2022 · Looking at BS7671:2018 Table 4D5 which is specifically for 70 °C Thermoplastic PVC cable (Twin & Earth) we have the maximum current caring capacities for various conductor sizes depending upon where they are installed and the amount of thermal insulation present, better known as ‘reference methods’.

Jun 13, 2016 · In our example we have an ambient temperature of 35 deg C (Ca = 0.94 From Table 4B1) and some thermal insulation in a stud wall but with the cable touching the inner surface of the wall (aka reference method 102 in table 4D5).

Feb 28, 2018 · Where cables are installed using these Installation Methods, the current-carrying capacity of the cables should be determined using Table 4D5 of Appendix 4 (70ºC thermoplastic insulated and sheathed cable with protective conductor).

Apr 25, 2021 · Table 4D5 Is this just for Twin and Earth, or would it also include 3 core and earth? Or would you use table 4D2A for three core and earth (flat cable)...
