What this splice does

The Morris 94434 is an inline compression (butt) splice intended to join two 400 MCM copper conductors end-to-end. It provides a mechanical and electrical connection when crimped with the appropriate die.

• Use: splice two 400 MCM copper conductors
• Configuration: short-barrel inline butt splice

Materials and corrosion protection

The barrel is formed from high-conductivity seamless copper and receives an electro-tin plating. The tin plating improves corrosion resistance while maintaining electrical conductivity.

• Base material: seamless copper
• Finish: electro-tin (tin-plated)

Safety and electrical rating

This splice is UL 486AB listed for use through 35 kV, indicating compliance with the UL standard referenced for electrical connectors of this type.

• Listing: UL 486AB
• Voltage rating: through 35 kV

Installation and crimping

Insert one conductor into each end of the barrel to the center stop, then crimp both sides using the blue-coded die. The barrel has a beveled entry to ease conductor insertion and printed crimp marks to help position the die.

• Beveled entry eases conductor insertion
• Crimp with Blue-coded die per printed marks
• Insert to center stop before crimping

Conductor compatibility

This specific SKU is sized for 400 MCM copper conductors only. Confirm conductor material and size before use.

• Compatible conductor size: 400 MCM
• Conductor material supported: copper (as specified)

Before You Order

Confirm the model number and quantity required before ordering. This SKU is specifically for splicing two 400 MCM copper conductors; do not substitute for other conductor sizes or materials.

• Verify conductor size (400 MCM) and material (copper) prior to purchase
• Ensure you have the correct blue-coded die and crimp tooling for installation
• Confirm required certification or project specifications reference UL 486AB through 35 kV
