Eaton BRPMIKCSR – Frequently Asked Questions

1) What does the Eaton BRPMIKCSR interlock kit actually do in a generator setup?
The BRPMIKCSR is a mechanical interlock for an Eaton BR plug-on neutral loadcenter. It physically blocks the main breaker and the generator backfeed breaker from being on at the same time, so utility power and generator power can never be connected to the panel together. That mechanical lockout is what lets a backfed breaker serve as the transfer means instead of a separate automatic transfer switch. It is a kit of hardware only, not a breaker and not a generator inlet.
2) Will the Eaton BRPMIKCSR interlock fit a plug-on neutral BR loadcenter?
Yes, that is the specific panel style it is built for. The kit is sold for Eaton plug-on neutral loadcenters and is rated to 225 A, which covers the common 125 A, 150 A, 200 A and 225 A BR plug-on neutral panels. Interlocks are panel-specific hardware, so confirm the loadcenter in front of you is a plug-on neutral BR type and not an older BR bolt-on-neutral or a CH panel before ordering.
3) Can I use this interlock kit on a 200 amp main breaker panel?
Yes. The 225 A rating on the BRPMIKCSR is the maximum main it is built to work with, so a 200 A plug-on neutral BR loadcenter is within range. Anything above 225 A main needs a different interlock.
4) Does the Eaton interlock kit come with the generator breaker and inlet?
No. The BRPMIKCSR is the interlock hardware only, shipped as a single kit. You still have to supply the two-pole backfed generator breaker sized to your generator, the power inlet box, and the feeder between them. Budget those as separate line items on the job.
5) Where does the generator breaker have to go when using a mechanical interlock?
At the top of the bus, in the two spaces directly below the main breaker on the same side the slide plate travels. The interlock plate moves between the main and that specific breaker position, so no other slot in the loadcenter will work. Plan the panel schedule around that before you start moving circuits.
6) Is an interlock kit or a transfer switch the better choice for a backup generator?
An interlock like the BRPMIKCSR is the low-cost route when the existing loadcenter is an Eaton plug-on neutral panel and you want access to every circuit in it, since the whole panel runs off the generator and you manage load by switching breakers off manually. A transfer switch is the choice when you want only selected circuits carried, or want the changeover automatic with no one on site. The interlock is manual by definition, so somebody has to be at the panel when the power drops.
7) Can I use a generic universal interlock plate instead of the Eaton BRPMIKCSR?
Not advisable. Interlocks are listed as part of the panel assembly, and an inspector on a permitted generator install will generally look for the manufacturer's kit for that loadcenter. The BRPMIKCSR is Eaton's own kit for plug-on neutral BR panels rated to 225 A, which is what keeps the panel listing intact. Aftermarket plates are a common cause of a failed rough inspection.
8) How much panel space does the Eaton BRPMIKCSR interlock take up?
The kit is listed at 1 inch in height, width, and depth, and weighs 1 lb. It mounts on the deadfront over the main breaker area rather than consuming breaker poles, so the space that matters on the job is the two pole positions you give up to the backfed generator breaker.
9) Is one BRPMIKCSR kit enough for a multi-unit building with several panels?
One kit covers one loadcenter. It ships as a single unit, so a property with separate metered panels per unit needs one kit per panel you intend to make generator-ready, plus a backfed breaker and inlet for each.
