Cumulative admittance (CA) to earth is tested and calculated at a point in time for each leakage. Feeding two currents with different frequencies and simultaneous testing evaluation of both frequencies and a mains frequency very quickly produces a calculation for leakage non-symmetry. A change in mains-frequency displacement voltage can act as a triggering criterion for calculating CA.

Dispenser box for a roll of continuous sheet material, produced by folding a sheet of semirigid thermoplastic material comprising five panels (11, 12, 13, 14) forming the longitudinal walls of the box, parallel to the axis of the roll, and flaps forming the transverse walls, comprises tongues (110, 130) extending from the flaps and forming means for locking the roll in place.
