See sectionRatings (page 149) for the rated currents.• Select a cable rated for at least 70 °C maximum permissible temperature of conductorin continuous use.• Make sure that the inductance and impedance of the PE conductor/cable (groundingwire) are rated according to permissible touch voltage appearing under fault conditions(so that the fault point voltage will not rise excessively when a ground fault occurs).• 600 V AC cable is accepted for up to 500 V AC.Guidelines for planning the electrical installation 61
