Eaton 3T20FB – Frequently Asked Questions
1) What wire sizes do the Eaton Series C 3T20FB terminals accept?
The Series C terminal kit, model 3T20FB, takes #14 through #10 AWG conductors and is rated for both copper and aluminum. If your feeder or branch run is #8 or larger, this is the wrong terminal size for that conductor.
2) Will these terminals work on any Eaton breaker, or only Series C?
These are pressure-type line and load terminals built for the Eaton Series C molded case circuit breaker platform. They are not a universal terminal, so match the breaker frame to Series C before ordering.
3) What does the 20A rating on this Eaton terminal kit mean for my install?
The terminals carry a 20A rating, matched to the 20A Series C molded case breaker. Use them on 20A frames only; a higher-amp breaker needs a terminal rated for that current and for the larger conductor it lands.
4) Can I use aluminum conductors with this Eaton terminal kit?
Yes. The terminals are rated Cu/Al for #14-10 AWG, so copper or aluminum in that size range lands directly without a separate transition connector.
5) Will an ABB OZXA-800 terminal kit work on an Eaton Series C molded case breaker?
No. The ABB OZXA-800 is a replacement terminal kit for ABB OT/OS600 and OS800 disconnect switches, so it is built around a different device platform entirely. The Eaton 3T20FB terminal kit supplies pressure type line and load terminals for the Eaton Series C breaker family, rated 20A and sized for #14-10 AWG Cu/Al conductors. Match the terminal kit to the device brand and series - terminal kits are device specific and are not cross-brand interchangeable.
6) How many terminals come in the Eaton 3T20FB kit?
Eighteen terminals ship per kit. That is enough to cover a number of breaker terminations at once, which is why it works as a shelf-stock item for maintenance electricians rather than a one-breaker repair part.
7) Is there a terminal kit like this for a disconnect switch instead of a breaker?
The Eaton 3T20FB is a breaker terminal for the Series C molded case platform. If you are terminating a disconnect switch, the ABB OT/OS600 OS800 terminal kit is the replacement component for those ABB switch frames, not a breaker accessory.
8) Will these terminals fit inside a tight panelboard enclosure?
Each terminal is small: .8 in wide, 1 in length/depth, and .7 in high. That low profile is what lets them sit in the breaker pocket without crowding conductors in a loaded panelboard.
9) What is a pressure-type terminal and why does it matter on a breaker?
A pressure-type terminal clamps the conductor under a screw-driven pressure plate rather than requiring a lug or crimp. On the Eaton Series C kit that means the stripped #14-10 AWG conductor goes straight into the terminal and is torqued down, with no added hardware to buy.
