XLPE 3×4+1×2.5mm2 Copper Cable Application
The structure of 3 cores+1 earth cable wire is designed for application where the earth wires are required according to customer requirements. This 3 core and earth cable/wire ais often referred 3 cores +1 cables XLPE insulated with voltage 0.6/1000v or IEC 60502 3 core and earth cable.
3 core plus earth cable has three conductors which are coded three different colors plus the earth. One of the main applications for this three core and earth lighting cable is when two way lighting is required, it provides the additional conductor between two switches operating the same light fitting.
