2.

If a conducting gate is used, a buried bonding
jumper must be installed across the opening
(Fig. 1-11).

3.

Where gates are installed, they shall be bonded to
the fence, grounding conductor or other bonding
jumper (Fig. 1-12).

4.

If the fence posts consist of a conducting material,
the grounding conductor must be connected to the
fence posts with a suitable connecting means
(Fig. 1-13).

5.

If the fence contains sections of barbed wire, the
barbed wire must also be bonded to the fence,
grounding conductor or other bonding jumper
(Fig. 1-14).

6.

If the fence posts consist of a nonconducting
material, a bonding connection shall be made to the
fence mesh strands and barbed wire strands at each
grounding conductor point (Fig. 1-14).

ERICO offers a complete line of welded connections
suitable for use with various shaped fence posts.
(Fig. 1-15). Any fence around a substation on the property
should be grounded and tied into the substation ground
system. If a facility fence meets the substation fence, it is
recommended to isolate the two fences to prevent any fault
in the substation from being transferred throughout the
facility using the fence as the conductor (Fig. 1-16). For
further discussion on fence grounding, see Chapter 6.
