Aluminum Two-Barrel Mechanical Connector — One-Hole 1/4″, 14–2/0 AWG (CU/AL)
Conversions Tech’s award-winning mechanical connector (SKU 210-99013) is a compact, two-barrel, one-hole lug engineered for fast, code-compliant terminations and taps. The tin-plated 6061-T6 aluminum body with chamfered wire entries streamlines insertion and delivers stable, low-resistance contacts across the full 14–2/0 AWG range for CU/AL conductors. Rated to 90 °C and up to 35 kV, it’s built for reliability in panels, PV BOS, and industrial gear.

Key Features
- Two-barrel, one-hole design (1/4″): Cleanly terminates parallels/taps using a single hardware stack — ideal when space is tight.
- Wide conductor window: Listed for 14–2/0 AWG, copper or aluminum conductors for maximum jobsite flexibility.
- Tin-plated 6061-T6 aluminum: Corrosion-resistant plating helps maintain low contact resistance in damp or outdoor enclosures.
- Chamfered wire entries: Easier insertion, less strand splay, improved mechanical retention.
- Thermal & electrical performance: 90 °C operating temperature; up to 35 kV class applications when used as listed.
- UL Listed: Meets rigorous pullout, thermal-rise, and corrosion criteria; supports CU/AL where indicated on the label.
- Panel-friendly geometry: Compact overall length ≈ 1-15/32″, pad ≈ 27/32″ × 1-1/4″ × 3/16″, height ≈ 1-1/32″ for dense gear.
Where it Excels
- Parallels & taps in service equipment, switchboards, and PDU/RPP panels.
- Solar PV / ESS BOS: Compact terminations at combiners, disconnects, and inverters; pair with listed grounding lugs for bonding.
- Industrial & OEM control cabinets where rework-friendly mechanical lugs cut tool time.

Installation Notes & Best Practices
- Verify listing & range: Confirm CU/AL, 14–2/0 AWG, and 1/4″ hardware fit before landing.
- Prep conductors: Strip clean; for AL, lightly brush and apply oxide inhibitor inside the barrel.
- Seat fully: Insert to back of barrel; ensure strands are not flared.
- Torque set screws to spec: Use a calibrated driver; document torque for QA/AHJ.
- Environmental checks: In wet/coastal installs, ensure proper enclosure rating and corrosion control.
Frequently Asked Questions
- Is this connector rated for both copper and aluminum?
- Yes — it’s listed for CU/AL conductors in the range of 14–2/0 AWG.
- What’s the mounting hole size?
- It’s a one-hole pad with a 1/4″ mounting hole for standard hardware stacks.
- What environments is it suitable for?
- The tin-plated aluminum body and 90 °C rating support typical indoor/outdoor enclosures when installed per listing and code. Use inhibitor with AL.
- Can I use it for taps or parallels?
- Yes — the dual-barrel layout is ideal for taps/parallels when permitted by code and the equipment label.
- What standards apply?
- See UL listing on the product and follow NEC (e.g., Article 250 for bonding/grounding; 230.46 for service line-side connections if applicable).
