The Fig 6 Type Irreversible Compression Connector is engineered for parallel conductor splicing in underground electrical distribution and grounding applications. Designed for two continuous parallel conductors, this connector accommodates wire ranges from 1/0 AWG through 250 MCM on the main run and 8 AWG through 6 AWG on the tap. Common installations include direct burial grounding grids, cathodic protection systems, and lightning protection networks where a permanent, maintenance-free connection is required.

Cross-Reference

Equivalent to Burndy and Blackburn parallel groove compression connector configurations, offering comparable electrical performance and installation characteristics at reduced cost.

FAQ

What wire combinations does this connector accept?

The Fig 6 accepts two parallel conductors: 1/0 AWG through 250 MCM on the main conductor and 8 AWG through 6 AWG stranded on the tap conductor. Both conductors must be copper.

Is this connector suitable for direct burial without additional protection?

Yes. The connector is rated for direct burial applications and is pre-filled with anti-oxidant compound to inhibit corrosion in underground installations.

What tooling is required for installation?

Installation requires a compression tool and dies appropriate for the connector class and conductor size. The irreversible design provides visual indication of proper compression once installed.
