Installation
Install Termination Compartment
Cover Panels
Carefully re-install the cover panels over each way by
inserting the tab at the back of the panel into the slot at
the bottom of the operating mechanism. See Figure 19.
When lowered to the horizontal position, tighten the pins
on the front of the panel to engage them with the front of
the enclosure.
Grounding
STEP 1. Connect the ground pads on each way to the
enclosure ground pad. Then, connect the
enclosure ground pad to the system ground in
accordance with the user’s standard practice.
See Figure 20, and Figure 21 on page 22.
If the switchgear is furnished with the con-
tinuous ground bus (catalog number suffix “-O”),
connect the ground bus to the enclosure ground
pad. Then, connect the enclosure ground pad to
the system ground in accordance with the user’s
standard practice.
Use the equivalent of 4/0 copper (or cable
sized in accordance with the user’s stan-
dard practice) in either a single or multiple
connection to realize the maximum momentary
rating of the switchgear assembly. For a multiple
connection, cables smaller than 1/0 copper or
equivalent should not be used.
STEP 2. Connect the cable concentric-neutral wires to
the grounding system as appropriate.
Figure 19. Install the cover panels over each way by inserting the
tab at the back of the panel into the slot at the bottom of the
operating mechanism.
