An electrical arrangement assembly is provided on the external region of a hermetic housing of a compressor. The arrangement includes an insulating box capable of housing an electrical interface between internal and external regions of the compressor including an insulating box coupled to the external region by means a hinge element having a pivot handle with an extension and a grounding tab. The grounding tab of the hinge element cooperates with a housing cradle of the insulating box when connecting the box to the housing of the compressor. A controlled angular movement between the insulating box and the hinge element results in electrical connection between a first and second set of electrical terminals of the electrical interface between the internal and external regions of the hermetic housing of the compressor.
