Thomas Betts 17278-TB Butt Splice Terminal Purple

Product Description

The THOMAS BETTS 17278-TB is a butt splice terminal used to join two wire ends in a single in-line connection. It is color-coded purple to indicate a specific wire gauge range, allowing technicians to quickly select the correct terminal during installation. Butt splice terminals are common in electrical, HVAC control wiring, and panel work where a secure, insulated wire-to-wire connection is required. Electricians, HVAC technicians, and other trade professionals install these as part of harness repairs, control circuit work, and field wiring tasks.

This terminal is suited for residential and light commercial applications where in-line wire splicing is needed. It fits into standard low-voltage and line-voltage wiring scenarios, including HVAC control boards, motor leads, and electrical panel feeders. The purple color coding follows industry-standard wire gauge identification practices, making it practical for organized, code-compliant wiring work.

Key Features

• Purple color coding for fast, accurate wire gauge identification at the point of installation
• In-line butt splice design joins two wire ends without additional connectors or junction hardware
• Compact form factor suitable for tight wiring spaces and harness repair work
• Sold individually with a minimum order quantity of 5 units

Compatibility

Designed as an OEM-style replacement butt splice terminal for use in standard electrical and HVAC control wiring applications where an in-line wire connection is required.

Installation Notes

Butt splice terminals are installed by electricians and HVAC technicians using a proper ratchet-style or hand crimp tool rated for the terminal type. Always de-energize the circuit and verify zero voltage before making or breaking any wire connections. Follow applicable NEC requirements for conductor splicing and insulation integrity. Do not use pliers or non-rated tools to crimp, as an improper crimp can result in a high-resistance connection or pull-out failure.
