Conversions Tech Split Bolt Connector – 3/0 AWG STR to 2 AWG SOL Copper Splicing
The Conversions Tech Split Bolt Connector is a versatile, heavy-duty electrical connector engineered for secure splicing and termination of copper conductors ranging from 3/0 AWG Stranded (STR) to 2 AWG Solid (SOL). Designed for dependable performance in both residential and commercial electrical systems, this connector provides a durable mechanical grip and low-resistance electrical path across a wide range of applications.
Featuring a robust split-bolt design, this connector applies uniform clamping pressure to conductors, ensuring long-term reliability even in environments subject to vibration, thermal cycling, and moisture. Available with tin-plated or nickel-plated finishes, it offers enhanced corrosion resistance for indoor, outdoor, and harsh-environment installations when properly insulated.

Frequently Asked Questions (FAQs)
1) What wire sizes does this split bolt connector support?
This connector supports copper conductors from 3/0 AWG stranded to 2 AWG solid.
2) Can this connector be used with both solid and stranded wire?
Yes. It is designed to accommodate both solid (SOL) and stranded (STR) copper conductors.
3) What materials are available?
This connector is available in copper or aluminum configurations depending on the application.
4) What finish options are offered?
Finish options include tin-plated and nickel-plated for corrosion resistance.
5) Is this connector UL and ANSI compliant?
Yes. It complies with applicable UL and ANSI safety and performance standards.
6) What temperature rating does this connector have?
The connector is rated for continuous operation up to 90°C (194°F).
7) Is this suitable for outdoor installations?
Yes, when properly insulated and installed in accordance with NEC and environmental requirements.
8) What tools are required for installation?
Standard electrical hand tools are typically sufficient for installation and tightening.
9) Does this connector provide a low-resistance electrical connection?
Yes. The split-bolt design ensures strong contact pressure and minimized electrical resistance.
10) Can this connector be reused?
Reuse may be possible depending on condition and application, but replacement is recommended for critical installations.
11) Is this connector insulated?
No. Split bolt connectors are uninsulated and must be insulated after installation if required.
