Burndy UGS350ULDB Unitap In-Line Splice Reducer, Direct Burial Rated

The Burndy UGS350ULDB is a Unitap Series in-line splice/reducer engineered for direct burial applications, giving installers a dependable way to connect and transition conductors below grade. Constructed from 6061-T6 aluminum and dual rated for both aluminum and copper conductors, this splice reducer accommodates a wide conductor range of 8 AWG-350 kcmil aluminum and 12 AWG-350 kcmil copper. Its direct burial rating makes it well suited for underground utility and distribution wiring where a compact, corrosion-resistant splice connection is required, and its mechanical design eliminates the need for specialized compression tooling on many installations.

Key Features

  • Conductor Range: Accommodates 8 AWG-350 kcmil aluminum and 12 AWG-350 kcmil copper conductors for flexible sizing and reducing applications.
  • Dual Rated Al/Cu: Approved for use with both aluminum and copper conductors in a single splice connection, simplifying inventory for mixed-metal jobs.
  • Durable Construction: Machined from 6061-T6 aluminum for strength and corrosion resistance in buried, high-moisture environments.
  • Direct Burial Rated: Engineered for below-grade installation, making it suitable for underground splicing without additional enclosures.
  • In-Line Splice/Reducer Design: Provides a compact, straight-line connection point for joining conductors or reducing conductor size within the connector's range.
  • Reducing Capability: Functions as a reducer, allowing transitions between different conductor sizes within the supported 8 AWG-350 kcmil range.
  • Unitap Series: Part of Burndy's Unitap line of mechanical connectors built for underground and direct burial applications.

Burndy UGS350ULDB – Frequently Asked Questions

1) Can the Burndy UGS350ULDB be buried directly in the ground without a splice box?
Yes. The UGS350ULDB Unitap in-line splice reducer is direct burial rated, so it can go below grade without an additional enclosure. That is what makes it usable on underground utility and distribution runs and direct-bury cable systems where there is no room or budget for a pull box at every transition.
2) What conductor sizes will the UGS350ULDB Unitap splice reducer accept?
It takes 8 AWG through 350 kcmil aluminum and 12 AWG through 350 kcmil copper. Because it is a reducer, the two ends do not have to match: you can land a large conductor on one side and a smaller one on the other as long as both fall inside those ranges.
3) Can I splice aluminum to copper with the Burndy UGS350ULDB?
Yes, it is dual rated Al/Cu, so an aluminum-to-copper transition in a single connector is an approved use. That is the common case on utility and distribution work where an existing aluminum feeder has to tie into copper. One connector covers both metals, so a crew stocking mixed-metal jobs does not need two part numbers.
4) Do I need a compression tool or hydraulic crimper to install this Burndy splice reducer?
No. The UGS350ULDB is a mechanical connector, and its design eliminates the need for specialized compression tooling on many installations. For a maintenance electrician or a small crew working out of a van, that means the splice can be made with hand tools instead of a hydraulic head and the matching dies.
5) What is the UGS350ULDB made of, and will it hold up in wet buried soil?
The body is machined 6061-T6 aluminum, chosen for strength and corrosion resistance in buried, high-moisture environments. That is the reason it carries a direct burial rating rather than a dry-location-only one.
6) Should I use an in-line splice reducer like this or a multi-tap connector?
An in-line unit such as the UGS350ULDB gives one straight-line connection point, so it suits joining two conductor runs end to end or stepping a conductor down in size. If you need to break one feeder out to several branch conductors, an in-line body is the wrong shape for that job and you want a multi-port tap connector instead.
7) Is the UGS350ULDB part of the Burndy Unitap family, and what is that line intended for?
It is a Unitap Series connector. Unitap is Burndy's line of mechanical connectors built for underground and direct burial work, so specifying within that series keeps a facility or utility crew standardized on one connector style across their buried splicing and reducing tasks.
8) What is the Burndy part number to order this direct burial splice reducer, and where do I get the spec sheet?
Order it as Burndy UGS350ULDB. The manufacturer spec sheet is published at https://hubbellcdn.com/specsheet/BRDY-UGS350ULDB-SPEC-EN.pdf, which is what to attach when a submittal package calls for the connector cut sheet.
