Eaton CC3225 – Frequently Asked Questions

1) Will the Eaton CC3225 main breaker kit fit my panel, or is it only for certain enclosures?
The CC3225 is a main breaker kit built specifically for Eaton Type ECC Unit Enclosures. It is not a universal main breaker, so if your load center or panelboard is not a Type ECC enclosure, this kit is the wrong part. The breaker itself measures 5.75 in wide by 7.75 in deep by 5.25 in high.
2) What size feeder conductors can I land in the Eaton 225A CC3225 main breaker?
Lug range on the CC3225 is #2/0 AWG through 300 kcmil, and the lugs are rated for both copper and aluminum conductors. That covers typical 225 A service feeders in either material. Anything smaller than #2/0 or larger than 300 kcmil will not terminate correctly in these lugs.
3) Is the Eaton CC3225 rated for a three-phase service?
It is a three-pole molded case breaker, so it switches and protects three conductors. The voltage rating is 120/240 V, which suits standard residential and light commercial services including 120/240 V three-phase four-wire delta. Do not apply it on a 480 V or 208Y/120 system where a higher voltage rating is required.
4) What does the CC designation mean on an Eaton 225A breaker, and how do I order the right one?
CC is Eaton's breaker frame type, and it is what determines whether the unit mounts in the enclosure. The part you order here is catalog number CC3225: CC frame, 3 poles, 225 amps. Matching the frame letter matters more than the amperage when you are replacing an existing main.
5) Can I use the Eaton CC3225 to replace a failed main breaker in an existing panel rather than buying a whole new load center?
That is exactly what this kit is for. It is sold as a main breaker replacement or upgrade for Type ECC Unit Enclosures, so a property manager or electrician can swap the main disconnect without replacing the enclosure, provided the panel is a Type ECC and the feeders fall in the #2/0 AWG to 300 kcmil lug range.
6) How much space do I need to allow for the Eaton 225A three-pole main breaker inside the enclosure?
Allow for a unit measuring 5.75 x 7.75 x 5.25 inches (width x depth x height). The depth is the figure most often overlooked when checking cover clearance and gutter space above the lugs.
