Buying Guide: Key Purchase Considerations
- Load requirements: Assess your total expected load and the number of circuits needed. Eight-space, 16-circuit panels are common for multi-room additions or major remodels, but plan for future expansion.
- Indoor vs. outdoor: For outdoor or damp locations, select a weather-rated enclosure (e.g., Type 3R) or a panel designed for outdoor use.
- Main lug vs. main breaker: Main lug panels are often simpler and allow downstream feeding from a main breaker elsewhere; main breaker options provide integrated protection.
- Neutral and ground bars: Ensure there is adequate space for neutrals and grounds, especially if you plan to add AFCI/GFCI breakers or tandem breakers.
- Compatibility with breakers: Verify that the panel supports the breaker types you plan to use (e.g., tandem, plug-on neutral, AFCI/GFCI options).
- Physical footprint: Measure available wall depth, mounting surfaces, and clearance for service access and wiring space.
- Installation and code compliance: Ensure the selected panel complies with local electrical codes and is installed by a qualified electrician if required.
- Expansion potential: Consider future additions to your electrical system, such as HVAC, workshop tools, or EV charging, and choose a panel that can accommodate it.
- Quality and warranty: Prioritize brands with established reliability and solid warranties to minimize long-term maintenance concerns.
