Sometimes especially the really good solutions turn out to be stunningly easy. Lugsulation by Hagemann Systems gives an example. Its name is composed of “lug” – as in cable lug – and “insulation”. Instead of just covering contacts with a cap – as it has been usual up to now – Lugsulation ensures their full insulation. Corrosion and fault currents become a thing of the past. Short circuits, which can inadvertently arise from a bare contact during assembly, are also excluded.
