FAQs

Which breakers fit this load center?

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 breaker planning?

This panel has 20 spaces and supports up to 40 circuits. Spaces are physical breaker positions, while circuit count affects how much branch-circuit expansion your electrician can plan without overfilling the panel.

Can this load center be installed outdoors?

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

Does this panel use plug-on-neutral breakers?

Yes, this panel is configured for plug-on neutral. That can simplify neutral connections with compatible AFCI/GFCI breakers, but your electrician should match the breaker type to the panel series and local code.

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

Cover: Included. 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.
