Replace selected breakers
An electrician installs Noble Carbon only where a project needs monitoring or control.
The product
Intelligence where the grid meets the home
Noble Carbon combines revenue-grade circuit monitoring, software-connected control, and a retrofit-ready breaker architecture inside the panel a home already has.
How it works
Start with selected circuits. Expand as the home electrifies
Measure and prioritize
Revenue-grade metering makes circuit demand visible while software establishes operating priorities.
Manage available capacity
The commercial platform will coordinate flexible loads to help the home stay within its electrical limit.

Current product and roadmap
Two form factors. One platform
We distinguish what is entering the pilot from the product designed for broad commercial distribution.
The Quad · four-inch form factor
The Quad is the hardware platform for the upcoming 200-home pilot. It provides circuit-level monitoring and control, with UL certification pending. Commercial availability is targeted for Q4 2026.
- Current pilot hardware
- Four-inch panel footprint
- Monitoring and software-connected control
- UL certification pending
The two-inch breaker
Noble Carbon plans to bring the platform into a compact two-inch form factor built for the contractor channel and constrained electrification projects.
- Field-configurable 15–50A design
- Modular circuit-by-circuit installation
- Broad retrofit compatibility
- Dynamic capacity management vision
Product specifications and availability remain subject to certification and final commercial configuration.
Planned capacity management
Flexible loads managed automatically
The planned commercial platform is designed to coordinate only the circuits identified as flexible—not indiscriminately turn appliances off.
Preferences establish priorities
Homeowners and installers identify which connected loads may be interrupted and establish operating priorities during commissioning.
Capacity triggers a response
When demand approaches the home’s electrical limit, the platform can temporarily pause a lower-priority flexible load.
Service restores automatically
The system is designed to restore the affected circuit as capacity returns, without asking the homeowner to monitor the panel.
A common circuit-level layer
Noble Carbon can complement communicating appliances and home-energy systems by reaching loads that do not share a manufacturer, protocol, or connected interface.
These automated capacity-management capabilities describe the planned commercial platform and are not included in the current Quad pilot configuration.
Connected ecosystem
Designed to work alongside device-level intelligence
Noble Carbon currently provides circuit-level monitoring and control through its own hardware and software. Our roadmap includes APIs and integrations that could allow Noble Carbon to coordinate with home-energy platforms, distributed energy resource management systems (DERMS), batteries, smart thermostats, and connected EV chargers—combining circuit-level visibility with device-level intelligence.
These integrations are planned and are not included in the current product.
What the platform enables
One breaker, several layers of value
For the homeowner
Complete an electrification project with less infrastructure work and gain clear, circuit-level visibility.
For the contractor
Convert capacity-constrained leads and add only the intelligence a project requires.
For portfolios
Understand distributed electrical loads without replacing every panel in a building portfolio.
For the grid
Turn installed circuits into measurable, controllable grid-edge resources over time.
Product questions
What exists today and what comes next
Does the current Quad automatically manage electrical capacity?
No. The Quad provides circuit-level monitoring and software-connected on/off control. Automated dynamic capacity management describes the planned commercial platform.
Will homeowners need to actively manage their circuits?
The planned commercial experience is designed to work from preferences established during setup, automatically pausing and restoring only designated flexible loads as capacity changes.
Who installs Noble Carbon breakers?
Noble Carbon products are intended to be installed and serviced by appropriately qualified electrical professionals in accordance with product instructions, listings, codes, permits, and local requirements.
Which electrical panels are compatible?
The platform is designed around 10 of 11 common residential panel families. Final compatibility depends on certified product listings, configuration, and the specific installation.
Is the product certified and available?
UL certification for the Quad is pending, with commercial availability currently targeted for Q4 2026. Timing and specifications remain subject to certification and production readiness.
