cover for energized bush-
ings. The cap can be used for per-
manent or temporary installation on
bushings, junctions or feedthru
devices that meet the requirements
of ANSI/IEEE Standard 386.
INSTALLATION
No special tools are required. A shot-
gun stick tool is used to place the
protective cap on an exposed bush-
ing interface. Refer to Installation
Instruction Sheet S500-21-1 for
details.
