be connected to the conduit before the enclosure. In lieu of a factory
supplied output lug, a lug rated for the appropriate voltage, current,
and conductor material, to be supplied and installed in the field, may
be used. Eaton's Crouse-Hinds Series NCGS Solar Cord Grips are
recommended for use with USE-2 and PV rated cable. Combined

6.3 INSTALL CONNECTOR
CAUTION
To ensure proper grounding, bonding between conduit connection is not
automatic and must be provided as a part of installation.
La liaison entre le cadre conduit n'est pas automatique et doit être
fournie dans le cadre de l'installation.
6.3.1 METALLIC CONDUIT
Place Myers hub through hole as shown in Figure 3 with the o-ring
on the outside of the enclosure. Screw on and tighten the locknut.
Next, screw on the grounding bushing, rotate to desired location
and tighten set screws. If ground hub configuration is used,
terminate ground wire to ground screw on locknut. If standard
configuration is used, screw on grounding bushing (Eaton's
Crouse-Hinds Series HGLL recommended). Rotate to desired
location, tighten set screw and terminate ground wire to ground
lug.
