Buying Guide: Key Purchase Considerations
- Shell type and enclosure: Indoor vs. outdoor, NEMA ratings, and corrosion resistance. Choose enclosures that match your environment and install location.
- Main breaker vs. main lug: Main breaker panels include a disconnect switch, simplifying serviceability. Main lug panels require a separate main breaker if required later.
- Electrical capacity and headroom: Verify the panel’s spaces and circuit limit aligns with current needs and potential expansion. Consider future additions to avoid another upgrade too soon.
- Conductor compatibility: Ensure the panel supports your wiring gauge and conductor types, such as copper bus bars and standard THQL/QO style breakers.
- Safety features: Look for dead fronts, secure enclosure latches, and clear labeling to minimize exposure to live parts during maintenance.
- Breaker compatibility: Confirm that the panel accepts standard breakers you plan to use (e.g., THQL, QO). Check for listing and compatibility notes from the manufacturer.
- Performance specs: A higher fault current rating (AIC) provides better protection against short circuits. Match the panel’s AIC rating to your electrical service.
- Installation flexibility: Panels with surface and flush mounting options or convertible configurations can simplify retrofits in existing spaces.
- Warranty and support: Manufacturer warranties and readily available replacement components can reduce long-term maintenance costs.
