CONDUCTIVE BAR WITH ANNULAR PORTION TO ACCOMMODATE TEST PLUG

A part (10) of an electrically conducting bar for an electrical apparatus， such as a terminal block (20) ， comprises a planar first portion (11) extending along a first extension direction (D1) and including a first area (12) arranged for allowing the setting up of a connection terminal (13) of the electrical apparatus intended to ensure an electrical contact between the first portion (11) and an electrically conducting element external to the apparatus. A first cutout (14) is arranged along a first contour (15) in the first portion (11) ， the folding of the first cutout (14) and the first contour (15) being configured in such a manner that the first cutout (14) forms a second portion (16) of the part (10) of electrically conducting bar extending protruding from the first portion (11) along a second extension direction (D2) forming an angle with the first extension direction (D1). Receiving elements (17) are formed in the second portion (16) and configured in such a manner as to separately accommodate a test plug (18， 19) external to the electrical apparatus and capable of an electric measurement of the second portion (16).
