Mount the CurrentGuard to the building structure using construction
methods and hardware appropriate for your site. Install the conduit
and pull the conductors as specified above or according to the engi-
neer’s design.
If desired, punch holes at this time for the conduit or nipple or
wait until the CurrentGuard is mounted to the building structure.
Punch holes only in the designated areas as shown in the following
illustration.

Conductor Sizing
Current Technology recommends installing CurrentGuard by using
the following conductor size for phase, ground and neutral connec-
tions. The conductor length should be as short as possible to ensure
the maximum level of protection. Use a larger conductor (not to
exceed the maximum allowed per a given model) where space and
bending radii permit.
Example of a SPD model number: CGP150-120/208-3GY

40kA units are shipped with #10AWG leads. Leads should be shortened
during installation in order to minimize conductor length.

60 through 200kA units are shipped with compression box lugs.
CAUTION: Careful consideration must be made when select-
ing an area for conduit entry. There are several components
inside the enclosure that may interfere with the conduit
entry path, therefore, ensure the path is clear of all objects
before drilling. Damages caused by installation errors are
not covered under the product warranty.
See Fig. 5 for conduit openings and enclosure dimensions.
