CEI 23-50 Standardization Sheet C2 Calibration Gauges for Simultaneous Contact Prevention Verification

This CEI 23-50 Standardization Sheet C2 Calibration Gauges for Simultaneous Contact Prevention Verification is a precision-engineered calibration instrument designed to validate the impossibility of simultaneous contact with live poles in sockets featuring collars or recesses, in strict compliance with CEI 23-50 standards. It functions as an essential safety verification apparatus for household and similar application sockets, ensuring socket designs effectively prevent unintended simultaneous contact with energized components—thereby mitigating electrical shock hazards and ensuring user protection during operation.
