FAQs

Which breakers should I use with this panel?

This panel accepts SN 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 my project?

This panel has 12 spaces and supports up to 24 circuits. That gives your electrician a planning limit for breaker positions and branch circuits without treating the panel as unlimited expansion space.

Is this panel intended for indoor installation?

Yes, this load center is intended for indoor placement. Your electrician should still verify the enclosure rating, mounting location, and inspection requirements for the jobsite.

Does this support plug-on neutral breakers?

Yes, this panel supports plug-on neutral breakers. That can simplify AFCI/GFCI neutral connections, but your electrician still needs to match the breaker series to the panel.

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

Cover: Not specified by the manufacturer contact the SuperArbor Pro Desk to confirm before ordering. Ground bar: 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.
