Eight Concentric Terminations
Eight concentric terminations may be installed in two stacked
groups of four, in close proximity, as shown in Figure 38. See
Figure 35 on page 32 for detailed information on clearances.
Lateral groups of four as shown in Figure 34 on page 32
may be a more convenient installation arrangement for multiple
groups depending on available space.

MULTIPLE CONCENTRIC TERMINATION ARRANGEMENTS
The illustrations on this page show some of the installation
arrangements for multiple concentric terminations that are
allowed.
See Multiple Concentric Termination Clearances on page
32 for detailed information on clearances and additional
arrangement options.
NOTE: When multiple concentric terminations are installed
through a roof in the same location all termination caps must be
at the same height measured from the ground.
Two Concentric Terminations
Two concentric terminations may be installed in close proximity
as shown in Figure 36 or with standard clearances when this
arrangement is not possible. See Figure 31 on page 32 for
detailed information on clearances. See Figure 32 on page 32
when installing three concentric terminations.
