Why Choose Select Equipment?

Selecting the correct bus plug is about more than matching amperage. Compatibility with the existing busway system, interrupting rating, voltage, configuration, and application are all critical factors. Our experienced team works with customers every day to ensure the correct replacement is identified before it ships.

When you work with Select Equipment, you receive:

  • One of the largest inventories of bus plugs in the United States

  • New and professionally reconditioned bus plugs

  • Support for many obsolete and discontinued product lines

  • Technical assistance identifying existing equipment

  • Engineering support for difficult replacement applications

  • Nationwide shipping

  • Fast response times for emergency breakdowns

  • Quality products inspected and tested before shipment

Our goal is simple: help you minimize downtime and restore power safely and efficiently.


What Is a Bus Plug?

A bus plug is a removable power tap that connects directly to an electrical busway (also called bus duct or busway distribution). Instead of running conduit and feeders throughout a facility, busway systems distribute electrical power through enclosed copper or aluminum bus bars. Bus plugs provide convenient connection points wherever power is needed.

Bus plugs are commonly used to supply power to:

  • Motor Control Centers (MCCs)

  • Industrial machinery

  • Manufacturing equipment

  • Conveyor systems

  • HVAC equipment

  • Distribution panels

  • Process equipment

  • Temporary equipment installations

Because bus plugs can often be relocated along the busway, facilities gain significantly more flexibility than with traditional hard-wired electrical distribution systems.


New, Reconditioned & Obsolete Bus Plug Solutions

Many industrial facilities continue operating busway systems installed decades ago. While these systems remain highly reliable, replacement bus plugs are often difficult to source because original manufacturers have discontinued many product lines.

Select Equipment specializes in supporting both current and obsolete busway systems.

Our inventory includes:

  • New bus plugs

  • Professionally reconditioned bus plugs

  • Surplus inventory

  • Hard-to-find and obsolete models

  • Replacement breaker bus plugs

  • Replacement fusible bus plugs

  • Custom sourcing solutions

If your existing bus plug is no longer manufactured, our team can often locate an equivalent replacement or recommend the most practical retrofit solution.


Types of Bus Plugs We Supply

Every facility has different power distribution requirements. We stock and source a wide variety of bus plug configurations, including:

Breaker Bus Plugs

Breaker bus plugs incorporate a molded case circuit breaker to provide overcurrent protection and a convenient disconnecting means. They are commonly used in manufacturing plants, commercial buildings, and industrial facilities where equipment protection and easy maintenance are priorities.

Fusible Bus Plugs

Fusible bus plugs utilize replaceable fuses to provide circuit protection. Many older industrial facilities continue operating fusible bus plugs because of their reliability and high interrupting ratings.

Disconnect Bus Plugs

Disconnect-only bus plugs provide a safe means of isolating equipment without integrated overcurrent protection when protection is located elsewhere in the electrical system.

Specialty Configurations

We also support numerous specialty configurations including various voltage ratings, ampacities, enclosure styles, and manufacturer-specific busway designs.


Manufacturers We Support

Our inventory includes bus plugs from many of the industry's most recognized manufacturers, including:

  • ABB

  • Siemens

  • ITE

  • Square D

  • Eaton

  • Cutler-Hammer

  • General Electric (GE)

  • Westinghouse

  • Federal Pacific

  • Bulldog

  • Crouse-Hinds

  • And many additional legacy and obsolete manufacturers

Even if your manufacturer is no longer producing replacement equipment, there is a good chance we can help identify a suitable solution.


Support for Obsolete Busway Systems

One of the biggest challenges facing industrial facilities today is maintaining aging electrical infrastructure after OEM support has ended.

Many facilities still rely on busway systems installed 30, 40, or even 50 years ago. While the busway itself may continue operating reliably, locating compatible replacement bus plugs becomes increasingly difficult each year.

Select Equipment has extensive experience supporting obsolete electrical distribution equipment. Our team works with customers to identify legacy products, locate replacement components, recommend retrofit options when appropriate, and help extend the service life of existing electrical systems.

Rather than forcing costly busway replacement projects, we often help facilities restore existing systems safely and economically.


Need Help Identifying Your Bus Plug?

Don't worry if the catalog number is worn off or missing.

Our specialists can often identify a bus plug using:

  • Manufacturer name

  • Busway model

  • Nameplate information

  • Voltage

  • Amperage

  • Photographs

  • Physical dimensions

  • Existing circuit breaker information

Simply send us photos of your existing equipment, and we'll help identify the correct replacement.
