2.0 Applicable Standards
2.1 All characteristics, definitions, and terminology, except as specifically covered in this
specification, shall be in accordance with IEEE Std 386™-2006 standard – Separable Insulated
Connector Systems. All connectors are to be fully shielded and submersible.
3.0 Construction
3.1 Rubber - High-quality, peroxide-cured EPDM Insulation shall be mixed and formulated at
molding location for complete control of raw rubber characteristics.
3.2 Junctions - The Clēēr loadbreak connector system shall include two loadbreak/deadbreak
junctions, each consisting of one 600 A loadbreak interface and one IEE Std 386™-2006
standard 600 A deadbreak interface.
3.3 Loadbreak “C” Connector – The 600 A loadbreak “C” connector (LCN) shall incorporate POSIBREAK technology, providing a layer of insulation over the conductive internal inserts and an
insulative sleeve on the base of the probes, resulting in increased strike distance and greatly
reducing the possibility of partial vacuum flashovers.
4.0 Installation
4.1 The Clēēr 600 A loadbreak connector system is available in both in-line and square
configurations. It shall be mounted directly to a vault, manhole walls or inside an enclosure.
The in-line junction assembly shall have an adjustable stainless steel bracket for mounting at
various operating angles. 600 A BOL-T, T-OP II, or BT-TAP cable terminations shall be
assembled to the source and load side 600 A deadbreak bushings following the instructions
provided in those kits. Using a clampstick, the LCN shall be assembled to the two center 600 A
loadbreak interfaces to complete the current path.
5.0 Production Tests
5.1 These tests shall be conducted in accordance with IEEE Std 386™-2006 standard. The values
from these tests are shown in Table 2 below:
 AC 60 Hz 1 Minute Withstand
 Minimum Partial Discharge Extinction Voltage
