Smart circuit breaker startup aims to cut EV charger installation costs
Noble Carbon has developed smart circuit breakers that dynamically adjust power to large appliances, avoiding the need for costly main panel upgrades. The breakers fit into existing panels and install in under five minutes, controlling the largest loads to keep total draw within capacity. The startup is one of 200 companies competing in TechCrunch's Startup Battlefield at Disrupt 2026.
Noble Carbon's technology addresses a significant financial hurdle in home electrification, where panel upgrades can double the cost of installing an EV charger. The company's approach targets the few high-draw appliances that create peak demand, rather than overhauling the entire electrical system. Their breakers dynamically manage power distribution, allowing existing infrastructure to handle new loads without expensive rewiring.
The startup's founders bring complementary experience, with CEO Jared Lebos drawing inspiration from South Africa's rolling blackouts and CTO Andrew Crane providing technical leadership. The company has moved beyond concept, with employees testing the breakers in their homes for over a year. They are currently pursuing UL certification and have partnered with utility Eversource for installations in up to 200 Massachusetts multifamily units.
This technology could meaningfully reduce barriers to EV adoption and home electrification for homeowners facing costly panel upgrades. By making installation more affordable, it may accelerate the transition to electric vehicles and appliances in older housing stock. Utilities could benefit from better load management across their grids, potentially reducing strain during peak demand periods. However, the product's real-world reliability and long-term safety will determine whether it gains widespread acceptance among electricians and homeowners.
