Comparison Schneider Sedna SDN5400170 graphite vs Legrand Valena InMatic 753078 black

For an ordinary household plug socket, wires with a cross section of 2.5 mm² are used. This type of wiring can withstand a power load of up to 3.5 kW for each of the outlets. Regarding sockets that serve large household appliances, their electrical contact group is designed for wires with a larger cross section.

The insertion depth of the socket must correspond to the depth of the mounting box. Usually, the standard installation depth is 40 mm. But there are models with both smaller and larger installation depths. For example, narrow sockets require only 25 mm depth from the back box. Additionally, there is a series of sockets that require at least 60 or even 80 mm depth from the mounting box.

This parameter is applicable to built-in electrical fittings. The thickness of the frame determines how much the outlet will protrude from the wall. In the average model, this figure is in the range of 7-10 mm. The thinner the frame, the more neat the socket will look.
