BL ACKBURN GROUNDING S YSTEMS — Overview The E-Z-Ground™ system — 01 This installation method results in a longlasting, 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.
