What this lug does

The Morris 90526 provides a mechanical termination for copper conductors within the specified wire range. Its offset tang positions the termination away from the mounting plane to clear adjacent hardware when needed.

• Made of copper for the lug body and intended for copper conductors.
• Offset design provides clearance from nearby terminals or busbars.

Typical applications

Appropriate where a copper termination with offset clearance is required, such as in electrical panels, switchgear, distribution blocks, or grounding/neutral termination points where space or alignment necessitates an offset lug.

• Panel and switchgear terminations
• Distribution and grounding connections
• Situations needing offset clearance from adjacent lugs or busbars

Installation and conductor termination

Insert the copper conductor under the arched pressure bar so it seats into the V-bottom collar, then tighten the steel-plated screw or bolt using a screwdriver, wrench, or pliers to form the mechanical connection.

• Accepts tightening with screwdriver, wrench, or pliers.
• Use copper conductors within the specified 500 MCM to 1/0 AWG range.
• Follow applicable electrical codes and project-specific torque or installation procedures.
