Eaton BRMIKBRBP – Frequently Asked Questions

1) Which Eaton interlock kit do I order for a plug-on neutral BR loadcenter versus an older BR panel?
Two different part numbers, and they are not interchangeable. For a plug-on neutral BR loadcenter, order BRPMIKBR. For a legacy (non plug-on neutral) BR loadcenter, order BRMIKBR. Both are 125A mechanical interlock kits for backfed BR loadcenters. Identify which panel generation you have at the panel interior before ordering, because the mounting on the two panel styles differs.
2) Does this Eaton interlock kit include the generator backfeed breaker?
No. The BR mechanical interlock kit is the interlock hardware only, the slide mechanism that physically prevents the main and the backfed generator breaker from being on at the same time. You supply the backfed BR branch breaker for the generator input, plus the inlet, cable, and any panel labeling the job needs.
3) Is my BR panel too big for a 125A interlock kit?
The kit is rated 125A, so it suits BR loadcenters at that main rating class. A 150A or 200A BR panel needs the interlock kit matched to that panel's main rating, not this one. Check the main breaker rating on the panel label first.
4) How does a mechanical interlock compare to a transfer switch for a generator hookup?
A mechanical interlock like the BR kit works inside the existing loadcenter: a sliding plate makes it physically impossible to close the generator backfeed breaker and the main at the same time, so you keep every circuit in the panel available and pick loads by turning breakers on and off. A transfer switch is a separate enclosure with a fixed set of transferred circuits and, in automatic versions, switches without anyone touching it. The interlock is the cheaper, smaller-footprint route when the panel is already an Eaton BR; a transfer switch is the choice when you need unattended automatic transfer or want a defined emergency circuit set.
5) Can I buy the Eaton BR interlock kit in a bulk pack for multiple units?
Yes. The legacy BR version comes as a single kit (BRMIKBR) or a 10-unit bulk pack (BRMIKBRBP), which is the one to spec if you are standardizing generator-ready panels across a portfolio or a multi-family build. The plug-on neutral version, BRPMIKBR, is sold singly.
