Maadoitetun

Maadoitetun is the genitive singular form of the Finnish adjective maadoitettu, which means grounded or earth-connected. It describes something that has been connected to the electrical earth or reference potential, usually for safety or stability in electrical systems.

The root comes from maadoittaa, meaning to ground or earth, and maadoitus, the act or state of grounding. In practical use, maadoitettua or maadoitetun are common in technical contexts such as electrical engineering, construction, and safety regulations. A maadoitettu laite (a grounded device) is designed to have a protective earth connection to reduce the risk of electric shock and to stabilize voltages during fault conditions.

Grammatically, maadoitetun is the genitive singular form of maadoitettu and is used to modify a noun in possessive constructions, for example maadoitetun laitteen (of the grounded device). It can appear in various cases as part of noun phrases, with the base meaning remaining tied to grounding or earth connection. The term is primarily technical; in everyday Finnish it may appear mainly in contexts describing equipment, installations, or safety features.

Related concepts include maadoitus (grounding or earthing), maadoitin (grounding conductor or electrode), and suojamaadoitus (protective grounding). While maadoitetun itself is a grammatical form, its use signals a description of objects or systems that have been provided with a grounding connection.
