The earth connection must be made with the largest possible cross-
section, with a low impedance, over a large area and via a short

the use of wide connections with large contact surfaces. Wide earth
straps are suitable for this. The table below illustrates typical suit-

Make sure that an optimally conductive connection is available at
the connection point for the protective conductor. To ensure this,
