Figure 10.
10.4.4 Separation between electric fence and physical barrier
Where a physical barrier is installed in compliance with 3 at least one dimension in
any opening should be not greater than 130 mm and the separation between the
electric fence and the physical barrier should be
• within the range of 100 mm to 200 mm or greater than 1 000 mm where at least
one dimension in each opening in the physical barrier is not greater than 130
mm;
• greater than 1 000 mm where any opening in the physical barrier has all
dimensions greater than 50 mm;
• less than 200 mm or greater than 1 000 mm where the physical barrier does not
have any openings.
Note 1
: These restrictions are intended to reduce the possibility of persons making
inadvertent contact with the pulsed conductors and to prevent them from
becoming wedged between the electric fence and the physical barrier,
thereby being exposed to multiple shocks from the energizer.
Note 2
: The separation is the perpendicular distance between the electric fence and
the physical barrier.
