Eaton CH4L125SP – Frequently Asked Questions

1) Does the Eaton CH main lug load center include a main breaker?
No. The CH load center is configured main lug only, so the feeder conductors land directly on the lugs and there is no main disconnect in the panel. That means overcurrent protection and disconnecting means have to come from upstream, either a main breaker at the service or a feeder breaker in the panel ahead of it. If you need service-entrance disconnecting means in the enclosure itself, a main breaker load center is the right choice instead.
2) Can this Eaton load center be mounted outdoors?
Yes. The enclosure is NEMA 3R metallic, which is the rating for outdoor and wet-location use, so it can hang on an exterior wall for a service panel, a pool or spa subpanel, or a detached garage feed. Note that not every part number in the CH main lug family is NEMA 3R, the R suffix designations such as CH4L125RP and CH8L125RP are the rainproof ones, while the SP versions are the indoor surface-mount style.
3) Can I use this Eaton load center as a subpanel in a multi-family building?
Yes, and that is the typical use for a main lug only panel. Feed it from a breaker in the upstream distribution panel sized at or below 125A, and that breaker serves as the overcurrent protection for the panel. In a subpanel you also have to keep the neutral and ground separated, which means adding a separate equipment ground bar since neutral bonding is not permitted downstream of the service.
4) What amperage and voltage is the Eaton CH main lug load center rated for?
125A, rated 120/240V single phase three wire, and it also carries 208Y/120 and 240V ratings. That covers a typical 120/240V residential or light commercial service and a 120/208V panel fed from a wye system in a multi-family or commercial building.
5) What is the short circuit interrupt rating on this Eaton load center?
25 kAIC. That is the fault current the assembly is rated to handle, which matters when the panel sits close to a large utility transformer or is fed from a big service where available fault current runs high. Get the available fault current from the utility or your short circuit study and confirm it lands at or below 25 kA at this panel location.
6) How many circuits does the Eaton 125A main lug load center hold?
The 8-circuit configuration gives you 8 spaces. Because Eaton CH breakers are available in tandem form in some ratings, the usable circuit count depends on which breakers you install and on whether the panel schedule permits tandems. Other part numbers in the CH main lug family carry different space counts, so match the part number to the number of branch circuits your panel schedule calls for.
7) Is this Eaton load center UL listed for use as a service panel?
It is UL Listed to UL 67, the standard for panelboards. Keep in mind this is a main lug only panel with no main breaker, so on its own it does not provide service disconnecting means. Used as a subpanel or with an upstream service disconnect, the UL 67 listing is what an inspector or institutional spec is looking for.
8) Which way do the feeder conductors enter this Eaton panel?
It is an overhead feed design, so the lugs are positioned for top entry. That suits a weatherhead drop or conduit coming down from above. If your feeder is coming up from below, from an underground lateral or a crawlspace, a bottom-feed arrangement will make for a cleaner install and shorter conductor runs inside the can.
9) Is the bus copper or aluminum in this Eaton load center?
Copper bus. For a property manager or facility electrician that matters in humid, coastal, or outdoor installs, where copper resists corrosion and carries better than an aluminum bus of the same size. Paired with the NEMA 3R metallic enclosure it is the combination you want for an exterior-mounted panel.
