Square D, Siemens, Eaton, and Leviton offer residential electrical panels, but a brand name alone does not determine the right choice. Compare the exact load center, approved breakers, required protection, room for future circuits, and the complete installation scope. A panel that fits your home's needs is more useful than a generic ranking of brands.
Start with the installation, then compare brands
A replacement panel and a service-capacity upgrade are different scopes. Before selecting equipment, an electrician needs to evaluate existing service capacity, the condition of the wiring and service equipment, available circuit spaces, and planned loads such as an EV charger or heat pump. An empty breaker position does not prove that the service can support another large load.
Ask for a proposal that identifies the model and circuit count, required protective devices, permit responsibilities, utility coordination, and any related grounding or service work. Compare those scopes before comparing the price of an empty panel enclosure.
How the main panel families differ
Square D: QO and Homeline
QO and Homeline are separate Schneider Electric product families with different breaker platforms. Schneider identifies copper bus construction and Visi-Trip indication among QO features. This does not establish that every QO breaker trips faster than every Homeline breaker under every fault condition. Protective-device performance depends on the exact device and its specifications. Use Schneider's QO/Homeline comparison to check model-specific differences.
Need a Panel Upgrade?
Outdated or overloaded electrical panels can present safety and capacity concerns. Our team evaluates 200-amp upgrades throughout Northern Virginia and confirms scheduling after reviewing the property. Call (571) 444-6886 to get started.
Eaton: BR and CH
BR and CH are distinct Eaton families, so specify which one appears in the quote. Eaton describes its CH loadcenters as using a silver-flash-plated copper bus. The CH line should not be described as having an aluminum bus with copper plating. Eaton also publishes a limited lifetime warranty for CH loadcenters and circuit breakers; the applicable written terms and exact product still control coverage. See Eaton's CH specifications.
Siemens
Compare the proposed Siemens model with the other quoted equipment on the same basis: service configuration, circuit spaces, approved breaker types, enclosure location, and availability of required protective devices. Brand-level claims such as superior reliability or better arc-fault protection need supporting evidence for the particular products being compared.
Leviton and smart features
Do not assume every Leviton installation includes circuit monitoring or remote control. Leviton describes smart capabilities as an upgrade involving compatible smart breakers and a Whole Home Energy Monitor interface. Ask which components are included, which circuits will be monitored or controlled, and what connectivity is required. See Leviton's service-change and smart-upgrade guidance.
Breaker compatibility: fit is not approval
A breaker snapping into a panel does not establish compatibility. The electrician must verify the panel labeling and the breaker's listing or classification for that specific application. Some classified replacement breakers are evaluated for specified panels made by other manufacturers, so a blanket claim that cross-brand use is never allowed is also inaccurate. Eaton describes its classified breakers; the specific compatibility documentation and application limits must be checked.
This is not a homeowner substitution guide. Do not remove the panel cover or change breakers to compare them. Share an exterior photo and the existing equipment information with your electrician.
Compare the features you will actually use
- Expansion: list planned equipment and ask how many usable spaces remain after the work.
- Protection: confirm the exact AFCI, GFCI, surge, and other protective equipment included where required.
- Replacement parts: ask how the proposed breaker family affects future repairs and additions.
- Smart functions: distinguish monitoring from control, load management, and backup-power integration.
- Location: confirm the enclosure is appropriate for the installation environment and available working space.
Separate equipment cost from installed cost
A retail enclosure price excludes much of a panel project: breakers, installation labor, related service work, permitting, and coordination. Use our published cost guide for planning and a free written estimate for your actual scope. Manufacturer warranties cover equipment under their own terms; AJ Long Electric provides a five-year workmanship warranty on quoted electrical installations.
Questions to ask before approving a panel
- What exact model and breaker family are included?
- Is this a panel replacement, a service upgrade, or both?
- Which future loads were considered?
- What work is included outside the panel itself?
- Which smart features and accessories are included?
- What are the separate equipment and workmanship warranty terms?
