European Thermoplast angle plug; grounded, white. You can connect household appliances with this grounded side input plug. The "ground" ensures that, in the event of a broken or disconnected wiring in a device (e.g. washing machine or computer), the metal parts are not supplied with current, the current is then fed into the earth via an additional earth wire. For connecting lighting and light equipment you need household cord with a core thickness of 0.75 mm2, for heavier equipment you need household cord of 1 mm2.
