Morris 90520 Copper Offset Lug, 175A, 3/0-4 AWG

Product Overview

The Morris 90520 is a copper mechanical offset lug designed to terminate 3/0–4 AWG copper conductors where an offset tang is required to clear adjacent terminals or busbars.

It features an arched pressure bar with a V-bottom collar for positive conductor contact, steel-plated screws to resist rusting, and a 600V rating with a 175A ampacity.

Key Features

• Copper construction for conductor and lug body
• Rated 175A and 600V
• Wire range: 3/0–4 AWG (copper conductors)
• Arched pressure bar plus V-bottom collar seats conductor for secure contact
• Steel-plated screw/bolt hardware to resist corrosion
• Offset tang to clear adjacent terminals or busbars
• Installable with screwdriver, wrench, or pliers

What this lug does

The Morris 90520 is a mechanical offset lug intended to terminate copper conductors and provide an offset connection point. The offset tang permits clearance from adjacent terminals or busbars when space or alignment requires the conductor termination to be set away from the mounting plane.

Applications

Use this lug where a 3/0–4 AWG copper conductor must be terminated and an offset is needed for clearance in panels, switchgear, or grounding/termination assemblies.

Connections and installation

Installation is straightforward: insert the copper conductor under the arched pressure bar so it nests against the V-bottom collar, then tighten the steel-plated screw or bolt to secure the conductor.

• Accepts 3/0–4 AWG copper conductors only
• Tighten hardware using a screwdriver, wrench, or pliers as appropriate

Electrical ratings

This lug is rated for 175 amps and 600 volts. It is specified for use with copper conductors; ratings reflect the manufacturer's stated ampacity and voltage.

• Ampacity: 175A
• Voltage rating: 600V

Mounting and mechanical dimensions

Confirm mechanical fit before ordering. The lug includes a 0.41" mounting hole and an offset tang profile to provide clearance from adjacent components.

• Mounting hole diameter: 0.41"
• Material: Copper (conductor and lug body); hardware is steel-plated

Before You Order

Confirm the model number and required quantity before ordering. Ensure conductor material and wire size match the lug's copper-only conductor specification and 3/0–4 AWG range.

• This lug is specified for copper conductors only—do not substitute with aluminum unless explicitly approved elsewhere.
• Verify the 0.41" mounting hole and offset tang clearance fit your panel or busbar layout.
