Burndy BIBS3504DB Unitap Direct Burial Submersible Multi-Tap Connector

Burndy BIBS3504DB Unitap Direct Burial Submersible Multi-Tap Connector

The Burndy BIBS3504DB is a Unitap™ direct burial, submersible multi-tap connector engineered for underground and wet-location conductor splicing. This single-sided, 4-port connector accepts dual-rated aluminum and copper conductors ranging from 12 AWG to 350 kcmil, and it is protected by an EPDM rubber covering with a pre-installed oxide inhibitor for long-term corrosion resistance in demanding underground and submersible environments.

Key Features

• Conductor Range: Accepts 12 AWG to 350 kcmil dual-rated aluminum and copper conductors, covering a wide range of job-site wire sizes in a single connector.
• Durable Construction: Copper connector body wrapped in a protective EPDM rubber covering that seals out moisture for direct burial and submersible use.
• Multi-Tap Design: Single-sided, 4-port Unitap™ body lets one main conductor tap up to four branch conductors from a single connection point.
• Direct Burial & Submersible Rated: Built to remain reliable below grade and underwater, where standard splice connectors are not suitable.
• Pre-Installed Oxide Inhibitor: Ships with oxide inhibitor already applied at the factory to protect aluminum-to-copper connections from corrosion over time.
• Color: Black EPDM rubber housing for straightforward visual identification in the field.
