enimmäisjohtamatkaa
Enimmäisjohtamatkaa refers to the maximum permissible distance a conductor can be run from its power source without experiencing an unacceptable voltage drop. This concept is crucial in electrical installations to ensure that appliances and equipment receive adequate power to operate efficiently and safely. The calculation of enimmäisjohtamatkaa takes into account factors such as the conductor's material, cross-sectional area, length, and the current it is expected to carry.
Exceeding the enimmäisjohtamatkaa can lead to several problems. A significant voltage drop can cause sensitive electronic
Electrical codes and standards, such as those found in Finland where the term originates, provide guidelines
