FAQ
What does "4-2 STR" mean for this connector?
4-2 STR refers to the stranding class of the conductor—specifically compact or compressed stranded cable with 4 to 2 strands per layer, common in 1/0 through 250 MCM copper and aluminum building wire. The connector barrel is sized to accept this stranding profile.
Is this connector rated for direct burial without a splice box?
Yes. The Fig 6 connector is specifically designed for direct burial applications and carries UL 467 listing for underground use. The copper alloy construction and pre-filled anti-oxidant inhibit corrosion in soil conditions.
Can I use this for lightning protection grounding?
Yes. The connector is UL 96 listed for lightning protection systems, making it suitable for bonding grounding electrodes to lightning conductors in accordance with NFPA 780.
