he following are solid wires and strands.

For single side outer hole types such as 221 series and 222 series,

Each connector is internally conductive! Therefore, live conductor, neutral wire and ground wire cannot be inserted into the same connector.

Failure to do so will result in a short circuit. Therefore, in any case, one for live conductor and one for neutral wire must be used.

This series is of cage spring structure and connected by operating handle. The following is usafe for your reference.

222: hard wire  0.08-4.0mm²,soft wire :0.08-2.5mm².

221 series :hard wire  0.2-4.0mm²,soft wire :0.14-4.0mm².
