A testing device for a multiple-pole socket is described, of the type comprising a connection body (1) provided with, a plurality of poles (C1-C5) which can be electrically coupled with the corresponding ones of said socket and provided with a plurality of light elements (S1-S5) corresponding to said plurality of poles (C1-C5), characterised in that electric connection means are further provided between said light elements (S1- S5) and said poles of the connection body (1) such as to power each light element (S1-S5) between a pair of poles (C1-C5) which represent either two current phases (F1-F3), or one phase and one neutral (N1) or one phase and one ground (T1). |
