Description
Features
- Engineered for a 100 Amp maximum capacity at 120/240 VAC, this main lug load center provides the robust, reliable power distribution required for demanding residential or light commercial applications. It is ideal for powering secondary structures like a detached garage, workshop, or outdoor living space, ensuring stable voltage delivery without overloading your main home panel.
- Built with a rugged, NEMA Type 3R rainproof enclosure, this load center is specifically designed for outdoor installation, effectively shedding rain, ice, and snow. The durable metallic construction resists corrosion, saving you from premature replacement costs and ensuring long-term safety and code compliance in exposed environments.
- This panel features a 3-space, 3-circuit configuration, specifically designed to accept standard QO circuit breakers. This compact layout eliminates guesswork during installation, providing the exact amount of space needed for dedicated, high-demand equipment like hot tubs, HVAC units, or EV chargers without paying for unused space.
- Featuring straightforward top or bottom feed capabilities with a fixed main lug design, this panel streamlines the wiring process to significantly reduce installation time. The spacious gutter room allows for clean wire management and easy manipulation of larger gauge conductors, minimizing the frustration of cramped terminations.
