Insulated Mechanical Connector (6 AWG to 350 MCM) — UL 486A/B Certified | Conversions Tech
The Conversions Tech Insulated Mechanical Connector is engineered for secure, low-resistance terminations and splices from 6 AWG up to 350 MCM. Built for demanding industrial, commercial, renewable energy, and utility applications, it features a rugged pre-insulated housing and a high-conductivity aluminum alloy body to support dependable power distribution. This connector is listed to UL 486A/B under UL File E531731 for code-compliant performance and long-term reliability.
Key Features
- Wide wire range: Accepts conductors from 6 AWG–350 MCM for high-capacity installations
- Fully insulated design: Dielectric housing helps reduce accidental contact and improves safety
- High conductivity: Premium conductive aluminum alloy helps minimize voltage drop and heat build-up
- UL listed: UL 486A/B (File E531731) for mechanical, dielectric, and thermal performance
- Corrosion resistance: Built to withstand oxidation, moisture, and harsh environments
- Fast installation: Compact, pre-insulated construction reduces field prep and labor time
Ideal Applications
- Service & distribution panels (feeders, tap points, and power distribution)
- Industrial machinery (reliable terminations in vibration-prone environments)
- Renewable energy (solar, wind, ESS where low-resistance connections matter)
- Commercial construction (multi-phase circuits and high-load electrical runs)
- Utility infrastructure (substations, grid tie, underground and high-amp conductors)
