Here are for solid wire.

Wire range within 2.5mm² / 4.0mm² / 6.0mm².There are 2-8 holes for choice.

Each connector is internally conductive! Therefore live wire,neutral wire, and ground wire can not insert into the same connector.

Otherwise it will cause short circuit.So in any case, one must be used for the live wire, one for the neutral wire.

These series are pluggable structure,just insert wires directly.
