Eaton CHP30B100X5 – Frequently Asked Questions

1) Will an Eaton Type CH 100A load center take my existing breakers?
Type CH is its own breaker footprint. The main breaker on this 100A loadcenter is a CH type, and the branch spaces are CH spaces, so it takes Eaton CH branch breakers. Eaton's other line, Type BR, is a different width and will not seat in a CH panel. If the breakers you are pulling out of the old panel are BR or another brand, budget for new CH breakers with the panel.
2) Is there an outdoor rated version of the Eaton CH 100A main breaker panel?
Yes, both indoor and outdoor enclosures are built. For a meter-adjacent service on an exterior wall, take an outdoor box; the R suffix box sizes (X/R, X2R, X5R) are the rainproof variants. Enclosure is metallic either way.
3) What size service conductors will land in the main lugs of a 100A Eaton CH panel?
The main breaker terminals accept #6 through 1/0 AWG. That covers the usual 100A service runs, including 1/0 aluminum SER and #4 copper. If your service entrance conductors are larger than 1/0, they will not land here and you need a bigger frame panel.
4) Can I feed an Eaton CH 100A loadcenter from underground service?
Feed type on this one is overhead, so it is set up for a service drop coming in at the top. A panel is fed from the end the enclosure and bus are arranged for, and swapping that on site is not a field change. For an underground lateral coming up from below, order the underfeed configuration instead.
5) Does a 100A Eaton CH panel work as a subpanel off my existing main?
It works as a subpanel. The 120/240V single-phase rating matches a standard residential or light commercial feed, and the integral 100A main breaker serves as the disconnecting means at the subpanel, which is what you want for a detached garage, a shop, or a tenant space in a multi-unit building. Remember to separate the neutral and ground bars when it is used downstream of the service disconnect rather than as the service panel.
6) Copper bus or aluminum bus in an Eaton CH loadcenter, does it matter?
The bus here is copper. It matters most in humid, coastal, or unconditioned spaces where an aluminum bus stack is more prone to oxidation at the breaker stab, and on panels that get loaded heavily and continuously. For a property manager standardizing across a portfolio, copper bus is the spec worth writing into the standard so every panel in the fleet behaves the same.
7) How wide is an Eaton CH 100A load center, will it fit between my studs?
Width is 14.31 inches. That is wider than a 14-1/2 inch clear stud bay at 16 inch on center leaves you once drywall returns are accounted for on a flush mount, so plan on cutting into the framing or surface mounting. Check the rough opening against 14.31 inches before you frame the wall.
8) Main breaker versus main lug loadcenter, which do I need for a service panel?
This is a main breaker unit, with the 100A overcurrent device built into the panel. That is what a service entrance panel needs, because the service requires a disconnecting means and overcurrent protection at the point of entry. A main lug panel has no main breaker and is only correct when it sits downstream of a breaker that already protects the feeder, or where a separate service disconnect is mounted ahead of it.
9) Can I use an Eaton CH 100A single-phase panel on a 208V three-phase building service?
No. This loadcenter is single-phase, 120/240V. On a three-phase service you would be feeding it from two legs of a 120/208V system, and both the phase rating and the voltage rating are wrong for that. For a three-phase distribution you need a three-phase panelboard, not a single-phase loadcenter. It is fine for a single-phase tenant feed pulled off a larger building service.
10) Which box size do I order for an Eaton CH 100A outdoor panel with 30 spaces?
Two things get specified together: the box size and the enclosure. Box sizes offered are X/R, X1, X2, X2R, X5, and X5R, and the R versions are the outdoor ones. Pole capacity tops out at 30. So an outdoor 30 space job takes one of the R boxes at the 30 pole rating. Main breaker type is CH at 10 kAIC across the whole range, so that part is not a choice you have to make.
