Custom Bussed Gutters

Custom Bussed Gutters

At Andrews Fabrication, we specialize in designing and fabricating custom bussed gutters that deliver efficient, reliable power distribution for commercial and industrial applications. Whether you need a high-capacity gutter for a new construction project or a retrofit solution for an existing system, our team can engineer a product that fits your exact requirements.

Bussed gutters serve as centralized pathways for distributing electricity across multiple circuits. These custom-built enclosures simplify complex electrical layouts, reduce material and labor costs, and improve long-term system maintainability. Every gutter is built to order, ensuring seamless integration with your switchgear, service entrance transitions, or custom NEMA enclosures.

Applications for Bussed Gutters

Our custom bussed gutters are ideal for:

  • Service entrance equipment

  • Multi-metering and tenant setups

  • Modular switchgear assemblies

  • Backup power and generator transitions

  • Main distribution from utility poles or transformers

These enclosures are common in multi-unit residential buildings, large commercial installations, electrical utility systems, and anywhere multiple loads must be fed from a central bus.

Built to Perform. Engineered to Last.

Our bussed gutter enclosures are fabricated using high-quality materials such as powder-coated steel, galvanized steel, or stainless steel—each chosen to suit your environment and required level of corrosion resistance. We offer multiple ampacity ranges, from 400A to 4000A+, depending on your application’s power demands.

Key design features include:

  • Heavy-duty enclosures rated for indoor or outdoor use

  • Precision-aligned copper or aluminum busbars

  • Termination points designed for field wiring access

  • Screw-on or hinged access doors for secure, easy maintenance

  • Compatibility with cable tap boxes and other components

Our fabrication team works closely with electrical engineers, contractors, and utility providers to ensure that all bussed gutter designs meet your electrical codes, project specifications, and installation requirements.

Common Applications

Custom bussed gutters are commonly used in:

  • Service entrance transitions – Create a secure and code-compliant link between utility power and building systems.

  • Main power distribution – Distribute electricity to branch panels or equipment from a central location.

  • Multi-tenant commercial buildings – Deliver power to separate units while reducing conduit and cabling complexity.

  • Industrial switchgear systems – Support operations in refineries, manufacturing facilities, and power generation plants.

  • Renewable energy installations – Seamlessly distribute power from solar panels, wind turbines, or backup generators.

Whether you’re working on a downtown high-rise or an industrial facility, our team will build a solution that fits your layout, timeline, and budget.

Seamless Integration with Your Electrical System

Each gutter we build is designed to work in harmony with your existing or new infrastructure. From service entrance transitions to walk-in switchboard rooms, we’ll ensure your gutter enclosure connects properly to surrounding panels and devices.

We also fabricate:

  • Back panel enclosures for component mounting

  • Walk-in enclosures for large-scale installations

  • Termination boxes for utility handoffs and grounding systems

When needed, our engineers can assist with CAD drawings and layout planning to ensure every connection point aligns perfectly on-site.
