FAQs

Which breakers fit this load center?

This panel accepts ES breakers. Mixing breaker brands or incompatible series can void the safety listing and fail inspection, so match the series your electrician specifies.

How do the spaces and circuits affect breaker planning?

This panel has 12 spaces and supports up to 24 circuits. Spaces are physical breaker positions, while circuit count affects how much branch-circuit expansion your electrician can plan without overfilling the panel.

Is this load center for indoor installation?

Yes, this load center is built for indoor placement. Outdoor electrical gear still needs the correct enclosure rating, mounting location, and inspection signoff for the jobsite.

Do I need plug-on-neutral breakers for this panel?

No, this panel is not configured for plug-on neutral. Use breakers and neutral wiring practices that match the panel series and the installation plan from your licensed electrician.

Does it include the cover, ground bar, or breakers?

Cover: Included. Ground bar: Not factory-installed. Breakers: Not specified by the manufacturer – contact the SuperArbor Pro Desk to confirm before ordering.

Best Use

Panel replacements where the service size matches the listed amperage.
Projects requiring the stated indoor/outdoor placement.
Jobs where the listed breaker series is already specified.

Electrical panel installation and replacement must be performed by a licensed electrician and typically requires a permit and inspection under local codes. Verify service size, breaker compatibility, and local code requirements before ordering.
