The given figures are intended only for preliminary estimation of the length of electric heating circuits.

For an accurate calculation, please contact ZAVOD GORELTEX CO. LTD.. To ensure safety and fire protection, a 30 mA RCD must be used.

If the design results in a higher earth leakage current, for devices with adjustable tripping current, the preferred tripping current level is 30 mA above the heating cable manufacturer's specified earth leakage current rating or the next available tripping current value for devices with non-adjustable tripping current, up to a maximum of 300 mA.
