Copper Long-Length Compression Splice — 4/0 AWG (≈212 MCM), Tin-Plated
Rugged copper compression butt splice engineered for 4/0 AWG (≈212 MCM) copper conductors. A seamless, tin-plated copper barrel with a center wire stop supports reliable multi-crimp terminations and low resistance in feeders, switchgear, and power distribution.
Key Features
- Long-length barrel: extra crimping surface for high pull-out strength and better heat dissipation.
- Seamless copper tube: smooth ID and chamfered entry for fast insertion and consistent make-up.
- Tin-plated finish: corrosion resistance for demanding indoor/outdoor enclosures.
- Purple color code: quick gauge identification in the field.
- 35 kV max (when properly installed) and 90 °C temperature rating.
- UL Listed and RoHS compliant.
Typical Applications
- Panelboards, switchboards, meter/main upgrades
- Industrial control panels, MCCs, wireways, bus work
- Solar PV, ESS/UPS, and telecom/data center DC
