Cables
WARNING
Before energizing the switchgear, replace the shipping
covers on all bushings and bushing wells with elbows
or insulated protective covers or caps. Failure to
replace the shipping covers on all bushings with
elbows or insulated protective covers or caps can
result in a flashover and serious personal injury
or death.
STEP 1. Remove the shipping covers from the
600-ampere bushing (yellow) or 200-ampere
bushing wells (orange). See Figure 9.
N OTICE
ALWAYS follow proper cable-installation
practices. When installing cable that will be
attached to the switchgear, provide a strain-
relief segment to minimize the load on the
bushings. Cables must be allowed to expand
and flex without putting a significant load on
the bushings. For a pit, either loop the cable
in the pit or bring it into the pit horizontally
and up to the gear at a 90° angle. Failure
to follow these precautions can result
in damage to the bushings and bushing
wells.
STEP 2. Install cable support brackets in accordance
with the appropriate reference drawing
included in the installation and operation
information kit. See Table 1.
STEP 3. Terminate the cables with user-furnished
separable insulated connectors, following the
manufacturer’s instructions.
Figure 9. Remove the shipping covers from 600-ampere
bushing—(yellow) or 200-ampere bushing wells (orange).
