My wall construction is such that between the OSB that closes my timber frame cassettes (on the inside), and the plasterboard of the wall, there is a 25mm gap (and 10mm+ of plasterboard). The socket box will screw to the OSB
Does this mean I should use a 35mm socket box, to finish flush-ish with the plaster, or is a 25mm socket box acceptable? Not sure if there is any rule about whether a socket face plate should be in contact with/form a lid of the socket back box?
