E-Z-Ground
™
compression connectors
represent a low cost, code-approved alternative
to welded ground grid connections. E-Z-Ground
connectors can be safely installed in half the time,
with fewer components, and in all weather
conditions. The range-taking capability of each
E-Z-Ground series connector translates to fewer
parts needed to complete the ground grid.
E-Z-Ground compression connectors are installed
using the “ABB Method,” which produces an easily
inspectable die embossment on the connector
indicating that the proper tool has been used and
successful crimp has been made. E-Z-Ground
carries the “ABB Method” mark of approval and
represents the connection of choice for faster,
simpler and safer ground grid system installations.

Meets all applicable specifications
ABB grid and ground rod connectors satisfy the
requirements of NEC
®
Article 250 for connecting to
the grounding electrode system. They also meet
the requirements of UL
®
Std. 467, UL Std. 486, CSA
Std. C22.2 No. 41 and CSA Std. C22.2 No. 65 being
acceptable as grounding and bonding equipment
suitable for direct burial. ABB grid and ground rod
connectors also satisfy the recommended practice
for the selection of grounding connector joints
described in the IEEE 837 standard for qualifying
permanent connections used in substation
grounding.
The connectors conform to the following IEEE
Standard 837 requirements:
• 350 °C current cycling
• Freeze-thaw test
• Accelerated aging – Nitric acid/salt spray
• Mechanical, tensile and electromagnetic force
(EMF) criteria

Reliable installations through
compression connections
The ABB method, utilizing compression tools with
matching dies, forms the connector and conductor
into a solid, homogeneous mass to provide an
optimum electrical bond between connector and
conductor. The dies are designed to produce a
circumferential, hex-shaped compression rather
than a simple indent. The circumferential
compression creates a large area of high-pressure
contact between cable and connector which, in
turn, ensures high conductivity, low resistance and
high pull-out values exceeding all industry
requirements.

01 This installation
method results in a long-
lasting, low-installed
cost connection. You
can install it and forget
it. Before compression,
typical cable connector
cross section of cable
and connector consists
of about 75% metal
and 25% air. After ABB
method compression,
the cross section
shows 100% metal with
virtually no air spaces.
