Eaton EAT-CHP20-150 – Frequently Asked Questions
1) Can the Eaton CH loadcenter be mounted outdoors on the side of a house?
Yes. The CH loadcenter comes in a NEMA 3R metallic enclosure, which is rated for outdoor and wet-location use against rain and sleet. It is built for overhead-feed service entrances, so the feeder enters from the top. If you are feeding from underground, a 3R top-feed configuration is the wrong choice for the install.
2) How many breakers will an 8-space Eaton CH panel actually hold?
Eight full-size spaces, or up to 16 circuits if you use tandem (twin) CH breakers in the spaces that accept them. That is the ceiling for the 8-space version, so if you are laying out a service with more than 16 branch circuits, size up rather than planning on tandems everywhere.
3) What size feeder conductors will the main lugs on this Eaton 200A panel take?
The main breaker terminals accept Cu/Al conductors in a #2 kcmil wire range across 3 wires. Both copper and aluminum feeders land in the same terminal, so you do not need a separate lug kit to run aluminum SER or URD to it.
4) Can this Eaton loadcenter be used as service equipment for an apartment building?
It is suitable for use as service equipment where no more than six service disconnecting means are provided. For multi-unit residential that means it works as an individual dwelling service or as part of a grouped arrangement staying within the six-disconnect rule. Beyond that you are into a service-rated distribution section instead.
5) Is this Eaton panel 120/240V single phase, and will it work on a three-phase service?
It is rated 120/240V single-phase. That covers standard residential and light commercial service. It is not a three-phase panel, so for a 208Y/120 or 480V three-phase feed you need a three-phase panelboard instead.
6) Is this Eaton CH panel a main breaker or a main lug panel?
Main breaker. An integrated CSR main circuit breaker gives you the service disconnect and overcurrent protection in the same can, which is what you need when the panel is the service equipment and there is no separate disconnect ahead of it.
7) What amperages does the Eaton CH NEMA 3R loadcenter come in besides 200A?
Amperage choices are 150, 200, 225, 300 and 400. The 200A version carries Eaton part number CHP08B200RF. Pick the rating off your service calculation and the utility's meter can, not off the breaker count, since the space count and the main rating are specified separately.
8) Does this Eaton loadcenter have a copper bus or aluminum?
Copper bus. On a panel that is going to live outdoors in a 3R enclosure, copper is the spec inspectors and utilities often prefer for conductivity and corrosion resistance, and it is worth confirming against the drawing if the job called out copper bus explicitly.
9) Does the Eaton CH panel come with a cover, or is that ordered separately?
The cover is included, so the panel arrives ready to install without sourcing a separate front. You still supply the branch breakers, which are CH-type, and any ground or neutral bar kit your layout calls for beyond what ships in the can.
