Considerations for Selection

1. Amperage Needs: Choose a panel that matches your home's total load requirements (100A for smaller homes, 200A for larger homes or heavy appliance use).
2. Breaker Type: Ensure compatibility with the brand and type of breakers you plan to install.
3. Location: Indoor panels are standard; outdoor-rated panels are available if installation requires exposure to weather.
4. Future Expansion: A 20-circuit panel provides moderate expansion capacity; consider a larger panel if you anticipate adding circuits in the future. A 20-circuit household distribution box is a reliable and versatile solution for residential electrical distribution, offering safety, flexibility, and compliance with modern electrical standards .
