Joint Integrity – ENATS 12-24 Cable Duct

Ridgiduct Power HV Class 1 cable duct is compliant with ENATS 12-24 Issue 3 which requires that the protective properties of the joints are not less than IP4X as specified by BS EN 60529. IP4X requires the joint as having protection against access to hazardous parts by a wire and should not be considered as an air or water tight joint. Polypipe PVCu Power HV Class 1 cable duct should be considered where a sealed system is required.
