Explanation of the mathematical addition of working voltages, insulationbetween circuits, and use of PELV, in TC 34 standards Ingestion-build-89079 Additional definitionsWhat is this standard about? This document is related to the insulation coordination in TC 34 standards and provides explanations on mathematical addition of working voltages, insulation between circuits, use of protective extra low voltage (PELV) and insulation between LV supply and control line conductors in order to cover new technologies associated with the use of LED light sources and controllable products. It describes in which way the addition
