Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

This 2-pole, 125A plug-in breaker is a smart choice when you need solid, code-compliant protection for large 240V circuits or when upgrading a panel to accommodate higher-capacity feeders. The dual-pole design ensures both legs trip together, reducing the risk of leaving a live, partially energized circuit in the event of a fault.

Practical considerations: - Ensure your panel is a Type BR model and accepts plug-in breakers of this rating. - Always de-energize the main power before installation or replacement and follow local electrical codes. - Plan for appropriate conductor sizing and protection per project requirements, using this 125A 2-pole combined with compatible wiring for 240V circuits.
