Product information
Introduction
Eaton terminates high-voltage underground cable to
deadfront apparatus such as transformers, switches, and
switchgear with its Cooper Power™ series 600 A 15 kV and
25 kV Class BT-TAP™ deadbreak connectors. They are fully
shielded, submersible, and meet the requirements of the
IEEE Std 386
™
standard— “Separable Insulated Connector
Systems”. Eaton’s 600 A deadbreak connectors are fully
interchangeable with all other manufacturers that also
certify compliance with the IEEE Std 386
™
standard. The
BT-TAP connector is rated for 900 A when used with all
copper current carrying components.

Read and understand the contents of this manual and follow
all locally approved procedures and safety practices before
installing or operating this equipment
Additional information
These instructions cannot cover all details or variations
in the equipment, procedures, or process described nor
provide directions for meeting every possible contingency
during installation, operation, or maintenance. When
additional information is desired to satisfy a problem not
covered sufficiently for the user’s purpose, please contact
your Eaton representative.
Acceptance and initial inspection
Each deadbreak connector is completely inspected and
tested at the factory. It is in good condition when accepted
by the carrier for shipment. Upon receipt of a deadbreak
connector, inspect it thoroughly for damage and loss
of parts incurred during shipment. If damage or loss is
discovered, file a claim with the carrier immediately.
Handling and storage
If the deadbreak connector is to be stored for an appre-
ciable time before installation, provide a clean, dry storage
area.
Quality standards
ISO 9001-Certified quality management system
All associated apparatus must be de-energized during
any hands-on installation or maintenance.
The 600 A BT-TAP Connector System 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.
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 contaminant’s
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.
The capacitive test point is not sufficiently accurate,
nor is it intended for, actual voltage measurements or
phasing operations.
A reading of no voltage from the test point should
not be the only indication of a de-energized circuit
obtained before touching the connector. Other
procedures can include direct conductor voltage testing
or grounding using a live-line tool.
