Electrical wiring. We are installing a cooker (vitro hot plate) and the wires are Black, Brown, Blue-Green and a stripey Green/Yellow one (230 v3.) We need to connect as follows according to the cooker: R-L1, S-L2, E and T-(N1/N2). Anyone know what colour wires corresponds to R, S and T wires or where to find the info? Many thanks.
