High-Voltage Connections
It is desirable to provide the sectionalizer with switches
and protection as shown in Figure 11. Surge protection
on both sides of the sectionalizer is recommended.
However, if provided on only one side, it should be on
the source side. In substations, surge protection should
be provided on the load side of the sectionalizer.
The universal clamp-type terminals used for main line con-
nections accept No. 2 solid through 350 mcm copper or
aluminum cables.
The parallel connector grounding clamp on the tank of
the Type GV and the cover of the GW sectionalizers will
accept No. 8 through No. 2 stranded wire.
120 Vac Wiring
A 120 Vac source voltage is required if the mechanism
cabinet heater and the potential charger for the trip
capacitor are to be energized.
The line voltage is connected to pins B and D of the
source-voltage plug shown in Figure 12.
Internal Wiring
A connection diagram for the GV and GW sectionalizers
is shown in Figures 12 and13.
