Is applicable to mobile insulating hoses with fittings used with hydraulic tools and equipment for live working at nominal voltages exceeding 1 kV r.m.s. at power frequency. Insulating hoses with fittings are used to provide a connection between the hydraulic tool and the pump which are at different potentials. They are not considered as a fixed component of a live working device (e.g. aerial device). They can be connected and disconnected under negligible pressure. They can be directly handled by the user.
