Buying Guide
- Panel type and location: Choose indoor or outdoor enclosures based on exposure, climate, and mounting location. Outdoor panels require weatherproof enclosures and appropriate weatherproofing in conduit runs.
- Main lugs vs. main breaker: Main lug panels are typically simpler and more cost-effective, while main breaker versions can offer integrated fault protection and centralized shutoff.
- Plug-on neutral readiness: If you plan to use AFCI or AFCI/GFCI breakers, a plug-on neutral-ready design simplifies wiring and future upgrades.
- Space and circuit capacity: 12-space, 24-circuit configurations balance a modest set of branch circuits with room for growth. Ensure the chosen panel supports tandem or quad breakers if needed.
- Grounding and bonding: Verify the availability of a sufficient ground bar and bonding provisions. Some panels include multiple ground slots or require additional accessory kits.
- Compatibility and expansion: Check whether the panel supports your preferred breaker brands and AFCI/GFCI options, as well as future expansion plans for feeders and subcircuits.
- Code compliance: Ensure the selected panel and configurations align with local electrical codes, including enclosure ratings, grounding, and enclosure protection requirements.
FAQ
- What is the difference between main lug and main breaker panels? Main lug panels distribute power to branch circuits and are fed from a separate main disconnect. Main breaker panels include a built-in main breaker for centralized shutoff.
- Is plug-on neutral required for AFCI breakers? Not always, but plug-on neutral designs simplify wiring when using AFCI or AFCI/GFCI breakers and can improve reliability in certain configurations.
- Can these panels be used outdoors? Only outdoor-rated panels (with NEMA or equivalent enclosures) are suitable for exterior installations. Indoor panels require proper protection from the elements.
- How many circuits can a 12-space panel handle? Typically up to 24 circuits with standard single-pole breakers; tandem or quad breakers may allow more in some spaces, depending on the model.
- Should I choose a 60 amp sub panel or a higher amp rating? The choice depends on your load calculation and future expansion plans. A 60 amp sub panel suits many residential needs, while larger garages, workshops, or additions may require higher capacities.
- Do these panels support grounding and bonding kits? Most listed panels have ground bars and bonding provisions; verify per model to ensure compatibility with your grounding plan.
