Bay Power supplies bus plugs for a wide range of busway systems, supporting both current production and legacy installations commonly found in commercial and industrial facilities. Whether you’re adding a new tap, replacing a failed unit, or matching an existing lineup, we help you identify and source the right bus plug quickly.

We support both fusible and circuit breaker bus plugs across common amp ratings and configurations, with solutions available for all leading manufacturers. From standard applications to hard-to-find and obsolete models, our team works to match your exact system requirements and minimize downtime.

Matching Your System — Without Guesswork

Bus plugs must match your existing busway system exactly. We help you verify compatibility and avoid costly mistakes by identifying the correct:

• Manufacturer and busway type

• Amp rating and voltage

• Mounting orientation and connection style

• Fusible vs. breaker configuration

• Required AIC ratings and protection requirements

We also supply the necessary circuit protection—whether that’s fuses (Class J, R, T, and more) or breaker-based solutions—so your bus plug arrives ready for installation.

Bus plug brands we regularly stock include Cutler Hammer, GE, Square D, Siemens/ITE, and even some obsolete models from manufacturers like Westinghouse, Crouse Hinds, Federal Pacific, Challenger, Continental, Sylvania, Arrow Hart, and Zinsco.
