i am currently installing some wiring and cannot find any reference to trunking recommendations.
i would like to understand size versus number of cables capacity
trying to fit the following in a trunking run
3cables 2 twin+earth 2.5mm + 1 twin+earth 1.5mm and
5cables 1 triple+earth 1.5mm + 4 twin+earth 1.5mm
what minimium size will be sufficient for each run
