Thomas Betts 54815 Butt Splice Terminal 350 Mcm

Product Description

The THOMAS BETTS 54815 is a non-insulated, crimp-on butt splice terminal designed for joining two conductors in a single inline connection. Built from copper with a tin (TiN) plating, this terminal accepts 350 MCM wire and measures 3.75 inches in overall length with an overall diameter of 0.95 inches. It is rated for two wire entries, making it a straightforward splice solution for high-ampacity conductors in industrial, commercial, and utility electrical work. Licensed electricians and wire harness technicians are the typical installers. The terminal meets CSA, UL, and RoHS requirements.

This butt splice terminal is used in applications where large-gauge copper conductors must be joined end-to-end without an insulated sleeve. Common install scenarios include service entrance work, panel feeder splices, motor lead connections, and other high-capacity wiring runs that use 350 MCM conductors. The non-insulated design is appropriate where the splice will be covered by a separate insulating sleeve, heat-shrink, or enclosure per applicable code.

Key Features

• Crimp-on connection type for fast, reliable conductor termination
• Copper contact material with TiN plating for corrosion resistance and conductivity
• Accepts 350 MCM wire with two wire entries for inline butt splicing
• Non-insulated body — compatible with field-applied insulating sleeves or heat-shrink
• 3.75 inch overall length, 0.95 inch overall diameter
• CSA Certified, UL Listed, and RoHS Compliant

Compatibility

Designed as an OEM-style crimp butt splice for 350 MCM copper conductors in commercial and industrial electrical installations requiring a non-insulated inline splice terminal.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before stripping conductors or seating the terminal. Use a calibrated crimping tool rated for the 350 MCM conductor size to ensure a proper mechanical and electrical connection. After crimping, apply an appropriate insulating sleeve or heat-shrink tubing over the exposed splice to meet insulation requirements.
