Product FAQs
5 answersWhat panels are compatible with the Eaton BJ2100?
The BJ2100 is designed for use in current Eaton Type BR load centers. It also serves as a direct drop-in replacement for main breakers in legacy Westinghouse and Bryant panels that accept BJ frame breakers.
How many panel spaces does the BJ2100 require?
This breaker requires four 1-inch pole spaces for proper mounting. It installs across the bus, taking up two spaces on the left and two spaces on the right side of the load center.
Can the BJ2100 be used as a sub-feed main breaker?
Yes, the BJ2100 is commonly used as a main breaker, a tenant main in group metering stacks, or a sub-feed main breaker to supply power to a downstream sub-panel.
Does the BJ2100 require a hold-down kit?
If you are installing the BJ2100 as a back-fed main breaker, the National Electrical Code (NEC) requires a compatible hold-down kit to secure it to the load center.
What is the difference between the BJ2100 and standard BR 2-pole breakers?
While standard BR 2-pole breakers take up two 1-inch spaces, the BJ2100 is a larger frame main breaker that requires four 1-inch spaces (two on each side of the bus) to handle main service applications.
