Recently I bought a couple of Metalclad 13A sockets from CCM.However,I see disparity between the listed models in the CCM(and also other Singapore distributors,so it is not CCM's fault) and the official MK site.On page 3 of the catalog of the Metalclad plus in the CCM website,the switched 13A and 15A sockets,and the rocker switches have SKUs that start with "G" instead of "K".These "G" series look different from the "K" series that is officially on the MK website.For example,on the SG distributer's pdf,the model of 2 gang 13A BS1363 socket is "G2946 ALM".However,on the official MK site,the model number is "K2946 ALM".The models have substantial differences such as the "G" version have narrower plastic edges around the socket holes,narrower rocker switch,only 1 earth connection at the back instead of 2 on the "K" series.The safety mark sticker also looks somewhat dubious(look like low quality sticker).Googling "G" series does not provide much information either.May I know the reason for the different models,where the "G" series are made in,and also where to get the "K" variants in Singapore. Thanks for any information about the matter. PS I see the "G" series installed on the void deck of HDB,but on Circle Line MRT stations,"K" series with red rockers are used.On a corridor on Jurong Point,there are also an MK Albany Plus socket installed on the wall with a more trust-able safety mark sticker on the top left.
