WARNING
All associated apparatus must be de-energized during
any hands-on installation or maintenance. Failure to
comply may result in death, severe personal injury and
equipment damage.
CAUTION
The 200 A loadbreak elbow connector is designed to
be operated in accordance with normal safe operating
procedures. These instructions are not intended to
supersede or replace existing safety and operating
procedures. The elbow connector should be installed
and serviced only by personnel familiar with good
safety practices and the handling of high-voltage
electrical equipment.
CAUTION
Optional Capacitive Test Point Operating Instructions:
Use only voltage indicating instruments specifically
designed for test points. Use of conventional voltage
sensing devices may provide false “No Voltage”
indications.
The test point must be dry and free of contaminants
when checking for voltage. After indication is taken:
clean, dry, and lubricate the test point cap with silicone
grease and assemble to the test point.
Always consider the termination to be energized until
the test point “No Voltage” indication is confirmed by
other means.
CAUTION
Elbows with tan cuffs (QuickMake probe) must be
mated only with 21.1 kV 1Ø rated bushings (identified
by tan nose pieces). Elbows with purple cuffs (3Ø
probe) must be mated only with 21.1/36.6 kV 3Ø rated
bushings (identified by purple nose pieces).
