Eight Concentric Terminations
Eight concentric terminations may be installed in two stacked
groups of four, in close proximity, as shown in Figure 35. See
Figure 32 on page 30 for detailed information on clearances.
Lateral groups of four as shown in Figure 31 on page 30 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 30 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 33 or with standard clearances
when this arrangement is not possible. See Figure 28
on page 30 for detailed information on clearances. See
Figure 29 on page 30 when installing three concentric
terminations.

Four Concentric Terminations
Four concentric terminations may be installed in close proximity
as shown in Figure 34. See Figure 30 and Figure 31 on page
30 for detailed information on clearances and additional
arrangement options.
