Abstract: The present disclosure relates to finger-safe requirements for breaker modules from electrical panel boards and envisages a finger safe cover 100a for a terminal of an electrical switching device 50. The finger safe cover comprises a cover body 110a with an expandable aperture section 120a. The aperture section 120a has an annulus 122a having a primary aperture 124a and a coupling section 126a surrounding the annulus 122a. The primary aperture 124a allows a thinner conducting cable 52 to pass therethrough. The coupling section 126a couples the annulus 122a with the cover body 110a. The aperture section 120a defines a secondary aperture 128a when the annulus 122a is detached from the cover body 110a by breaking the coupling section 126a, to allow to pass therethrough a thicker conducting cable 54. The cover 100a passes the IPXXB test, eliminates the need of safety accessories and is easy to install.
