• Screw connection
Screw clamps are designed acc. to EN 60999-1 / VDE 609-1.
Chart 1 below shows the screw size depending
on wire size and the required clamping and testing
torque..

Diagram 1 below shows the range of tensile strength for a screw
connection with a clamp screw M3, fastened with a torque of 50
Ncm, depending on the wire size.

Wire gauge
This comparison chart allows a cross reference between American
Wire Gauge (AWG) and metric wire sizes (mm

It has to be noted that wires of the same AWG number but with
different composition have slightly different mm
