Eaton 3BR2442LC150 – Frequently Asked Questions

1) Does the Eaton BR three-phase loadcenter come with a main breaker, or is it main lug only?
Main lug only. The Eaton BR three-phase loadcenter uses a main lug design, so the feeder conductors land directly on the bus lugs and overcurrent protection has to come from upstream, typically the breaker in the panel or switchgear feeding it. If you need the disconnect at the panel itself, a main lug unit is the wrong choice and you want a main breaker loadcenter instead.
2) Will a NEMA 1 loadcenter work outdoors or in a wash-down area?
No. The NEMA 1 enclosure on the Eaton BR three-phase loadcenter is indoor only, rated for protection against dust and incidental contact. It has no rain, sleet or hose-down rating, so an exterior wall, a parking structure, a mechanical yard or a food-service wash area all need a rainproof or watertight enclosure instead. Dry indoor electrical rooms, utility closets and back-of-house areas are what it is built for.
3) What size feeder conductors can I land in the Eaton BR three-phase panel?
The lugs take #6 through 3/0 AWG, which covers the usual copper and aluminum feeders on the smaller ratings in this family. Check the conductor size your engineer sized for the feeder before you set the panel, because anything above 3/0 will not land in that lug range.
4) Is this a 3-wire or 4-wire panel, and can I get a neutral for 120V branch circuits?
It is a 4-wire three-phase loadcenter, meaning three phase conductors plus a neutral. That lets you run 120V single-pole branch circuits off the panel as well as three-phase loads like motors and package HVAC units, rather than being limited to a 3-wire delta arrangement.
5) How many circuits does the 125A Eaton BR three-phase loadcenter hold?
The 125A configuration, model 3BR1224LC125, is a 12-space panel that will accept up to 24 circuits when tandem breakers are used in the spaces that allow them. Count your full-size two- and three-pole breakers first, since a three-pole breaker for a motor or rooftop unit consumes three spaces.
6) Aluminum bus or copper bus, which one should I order?
Both are offered across the Eaton BR three-phase main lug family, depending on the configuration. Copper bus is what most institutional and healthcare specs call for and what you standardize on where the drawing states copper; aluminum bus is the common commercial choice. If the electrical spec on the job sheet names a bus material, match it, because the bus is not field-changeable.
7) Is the Eaton BR three-phase loadcenter UL Listed for a permitted commercial job?
Yes, it carries a UL Listing, which is what an inspector looks for on a commercial or institutional installation. That covers the enclosure and bus assembly as a listed unit, so keep the branch breakers to the ones Eaton lists for BR loadcenters to keep the assembly compliant.
8) Which Eaton model numbers should I quote for a 400A or 600A three-phase main lug panel?
The 400A is Eaton 3BR4242LC400S and the 600A is 3BR4242LC600S. Both are the larger 42-space frame in this main lug family, so they are the ones to quote when a distribution panel needs high circuit count and a big feeder rather than a small 12-space unit.
9) Can I use this three-phase loadcenter for a shop with motor loads and a rooftop HVAC unit?
That is exactly its use case. The three-phase 4-wire configuration gives balanced power for motor loads and commercial equipment, and it suits light industrial shops, retail with three-phase HVAC, multi-tenant buildings, professional offices and school or institutional buildings. Size the panel to the feeder and confirm you have enough spaces for the three-pole breakers those units require.
