The "Normpositionen-Katalog" (NPK) is one of the most important products of EIT.swiss for the industry. Using this catalogue, planner, architects and electricians get relevant information and benchmarks for approx. 14.000 items. As an established calculation tool, the NPK is meant for creating precise and detailled service specifications and calculations. EIT.swiss updates their NPK products every year.
