You can trust Bay Breakers to get you the bus plug you need, quickly. We've specialized in new, used, obsolete, and hard to find electrical products for over 20 years. All of our bus plugs, new or reconditioned, feature a full 1-year replacement warranty.
We regularly stock circuit breaker style bus plugs and fusible style bus plugs, with or without neutral and ground, 3 Phase configurations for 3 wire or 4 wire, and all other busway components and fittings you'd need for your project. For circuit breaker type bus plugs, you'll need to know the AIC rating of the system.
