What Is Surplus Electrical Equipment?

Surplus electrical equipment refers to unused, excess, or overstock electrical components that businesses sell at reduced prices.

These components include circuit breakers, transformers, switchgear, motor control centers, and other electrical supplies and materials in electrical systems. Surplus equipment differs from used equipment because it typically hasn’t been installed or operated.

Common sources include:

• Canceled construction projects
• Warehouse liquidations and closures
• Manufacturing overruns and excess inventory
• Facility upgrades and replacements

Many contractors miss opportunities to save money on quality components because they don’t understand the surplus equipment market.
