It ships with a 100A main breaker and included breakers to get a starter setup running. The unit emphasizes longevity with galvanized steel and tin-plated copper bus bars. A self-adjusting dead front enhances safety during panel access, and the kit approach helps streamline installation for new or upgrading systems.
Leviton 20-Space Indoor Load Center With 100A Main
Leviton’s LP210-BPD 20-space indoor load center combines easy rough-in wiring with organized, tidy cabling via notches stamped for cable ties. It ships with a 100A main breaker and uses tin-plated copper busbars for enhanced conductivity. This panel is positioned for residential installations and light commercial projects where straightforward wiring and reliable performance are priorities.
Introduction to 100 Amp Feed-Through Panels
100 amp feed-through panels distribute power efficiently while offering room for future expansion. They are commonly used where main service equipment must feed multiple branch circuits without heavy overhauls. Key considerations include enclosure type (indoor vs. outdoor), bus material, breaker compatibility, and whether a main breaker or plug-on neutral design best suits the installation. The five options above cover a spectrum from rugged outdoor to compact indoor configurations, enabling informed choices based on location, cabinet style, and desired expansion path.
Buying Guide: Key Purchase Considerations
- Application environment: Outdoor panels require weather-resistant enclosures (NEMA 3R or better) and corrosion-resistant bus bars. Indoor panels prioritize compactness and easy access.
- Main and circuit layout: Decide between main breaker panels, main lugs, and plug-on neutral designs. Ensure the number of spaces matches your circuit needs and potential future expansion.
- Breaker compatibility: Confirm that the panel accepts the intended family of breakers (e.g., QO, HOM, QP) to simplify future replacements and upgrades.
- Grounding and bonding: Look for defined ground bars and proper bonding connectors to meet code requirements and safety standards.
- Ease of installation: Consider panels with clear labeling, included grounding components, and simple wire routing to reduce installation time and error.
- Safety features: Self-adjusting dead fronts, accessible neutral bars, and secure enclosure designs improve installer safety and reduce accidental contact with live parts.
- Cost of ownership: Factor in long-term maintenance, availability of replacement breakers, and compatibility with existing electrical service equipment.
