Morris 90993 Offset Solid Pin Terminal, 600 MCM Wire / 400 MCM Pin

Product Overview

The Morris 90993 is an offset solid pin terminal connector that terminates a 600 MCM conductor to a 400 MCM solid pin.

Constructed of tin‑plated aluminum with a barrel pre‑filled with oxide inhibitor and supplied with an EPDM insulating cover; rated for 600 V.

Key Features

• Offset solid pin design for adapting larger conductors to smaller equipment pins.
• All‑aluminum construction with tin plating for compatibility with aluminum and copper conductors.
• Barrel pre‑filled with oxide inhibitor to help protect the conductor/terminal interface.
• Die index and crimp marks on the barrel for correct crimp placement.
• Supplied with an EPDM insulating cover (color code: yellow).
• Voltage rating: 600 V.

What this terminal does

The Morris 90993 adapts a 600 MCM conductor (aluminum or copper) to a 400 MCM solid pin. Its offset solid pin geometry provides a physical interface for landing the larger conductor onto smaller equipment pins or lugs.

• Purpose: reduce conductor size for connection to breakers, switches, panelboards, and lug terminals that accept a 400 MCM pin.
• Offset pin allows clearance or alignment where a straight pin would not.

Typical applications

Use this terminal where a larger feeder conductor must be terminated to a smaller equipment pin. The product is intended for use in electrical distribution equipment connections.

• Commonly used with breakers, panelboards, switches, and lug terminals that require a 400 MCM solid pin.
• Suitable for both aluminum and copper conductors when installed per recommended practices.

Materials and conductor compatibility

The terminal is all‑aluminum with a tin plating on the barrel. The barrel is pre‑filled with oxide inhibitor to help protect the conductor/terminal interface.

• Material: aluminum body with tin plating.
• Conductor compatibility: aluminum or copper conductors (use appropriate installation technique for each).
• Color code: yellow EPDM insulating cover supplied with the terminal.

Installation and crimping

Install the terminal by stripping the conductor, inserting it fully into the barrel, and crimping at the marked die index. After crimping, slide the supplied EPDM insulating cover over the completed connection.

• Barrel includes die index and crimp marks to indicate correct crimp location.
• Barrel pre‑filled with oxide inhibitor—ensure conductor is fully inserted so inhibitor contacts the conductor.
• Follow accepted crimping practices and manufacturer tooling/wrap recommendations for 600 MCM terminations.

Before You Order

Confirm the model number and quantity required before ordering. Ensure the 600 MCM to 400 MCM size transition and the tin‑plated aluminum construction meet your project and code requirements.

• Verify that equipment accepts a 400 MCM solid pin.
• Confirm installer tooling and crimp dies match the die index/crimp marks for 600 MCM terminations.
• If in doubt about compatibility with specific equipment or local code requirements, consult an electrical engineer or authority having jurisdiction.
