6. The contact voltage the voltage between component (e.2.6.1 Step voltage The step voltage the voltage between person’s feet placed apart. the conductor) and earth potential. This is particularly required areas with groups people.2/50 μs) rain and fulfils the requirements for touch protection according IEC/EN 62305-3. with pulse voltage min. The isCon® conductor Pro+ was tested a length max. Here the current flows between the person's feet through their body. These voltages need reduced via potential control insulation. 2.2 Protection against dangerous touch voltage The isCon® conductor Pro+ can used as protection against dangerous touch voltage.g. 100 kV (1.
