TECHNICAL INFORMATION 4 Wiring

4.1 Cable connection

In general, flexible copper cable is used for wiring the inside of a switchboard For an operating voltage of less than half the cable insulating voltage or in other words < 500v , these cable are treated as belonging to lass Consequently they may be secured directly to metal supports without inserting an insulator.

4.2 Lug crimping

A lug should only contain a single power cable, all the strands of the conductor should be located inside the lug barrel.

Used crimp tools, of a suitable size , as recommended by the lug manufacture Apply the tightening force specifited by the manufacture of the crimp too Tools should be checked at regular intervals.
