Eaton T400DA2 – Frequently Asked Questions

1) Will the Eaton T400DA2 terminal fit my molded case breaker?
The Eaton Series C T400DA2 pressure terminal is built for type LB molded case breakers in the Frame J-K size. If your breaker is a different frame or a different type designation, this terminal is not the right lug kit for it. Match the frame letter on the breaker label before ordering.
2) What wire size can I land in this Eaton Series C breaker lug?
Each terminal takes two copper conductors sized #3/0 AWG through 250 kcmil. That is a copper-only range, so aluminum feeders need a different lug. The two-conductor capacity is what makes it usable for parallel feeder runs into a 400 A breaker.
3) How many terminals come in the Eaton T400DA2 kit?
It ships as a 2-piece accessory terminal set, so one kit covers two poles. A three-pole breaker being relugged at both line and load ends needs more than one kit, so count your poles and ends before you order.
4) Is this Eaton pressure terminal UL Listed for commercial panel work?
UL Listed, yes. That matters on inspected commercial and industrial distribution work where the lug has to be a listed part of the breaker assembly rather than a field-improvised connector.
5) Will the T400DA2 lug clear the gutter space in my panelboard or enclosure?
The terminal body measures 1.5 in wide, 2.3 in long/deep and 1.4 in high. Add conductor bend radius for #3/0 to 250 kcmil copper on top of that when you check wire-bending space at the breaker.
6) Can I use the Eaton T400DA2 to relug an existing breaker during a retrofit?
Yes, that is a normal use for it. Replacing damaged or undersized lugs on an existing type LB Frame J-K Series C breaker is straightforward with this 400 A terminal set, provided the feeders fall in the #3/0 AWG to 250 kcmil copper range.
7) Is this a standard pressure terminal or a compression lug?
Standard pressure (mechanical) terminal. The conductor is stripped and clamped under a set screw, so no crimp tool or compression die is needed on site, unlike a compression lug kit that requires a hydraulic crimper.
8) What is the exact part number to order for this Eaton 400 A breaker terminal?
Order Eaton part T400DA2. It is the Series C standard pressure terminal rated 400 A for Frame J-K type LB breakers.
