Tightening torquesTerminal cross sectionsConductor type
3 – 4 Nm2.5 mm² to 6 mm²Solid wire and stranded
3 – 4 Nm1.5 mm² to 4 mm²Fine stranded
For fine stranded (flexible) wires, connection is made via cable lugs/ring terminals. When connecting
two individual wires with a U-bracket, cross sections have to be identical.
