Leviton LB230-GST 2nd Gen Smart GFCI Breaker - Remote Control

Our review of the Leviton LB230-GST 2nd Gen smart GFCI breaker finds it best suited for homeowners and electricians who want remote control, enhanced safety, and circuit-level energy visibility in a Leviton Load Center. The bottom line: this 2-pole 30 amp breaker combines a built-in ground fault trip with smart ON/OFF control and app integration, so users can schedule circuits, remotely power appliances, and monitor consumption when paired with the required Whole Home Energy Monitor. It is a clear choice where compatibility with the Leviton ecosystem and plug-on installation are priorities.

Key Features

• Smart integration: Works with the My Leviton app to provide remote control and scheduling of the breaker from a phone for convenience and energy savings.
• GFCI protection: Built-in ground fault circuit interrupter offers enhanced safety on 120/208 and 120/240 VAC branch circuits where ground fault protection is required.
• Remote ON/OFF: The breaker can be turned on or off remotely, which is useful for hard-to-reach circuits or to disable equipment for safety and energy management.
• Plug-on installation: The plug-on design supports installation at rough-in without breakers present, simplifying wiring and later breaker addition.
• Whole-home visibility: When used with Leviton's Whole Home Energy Monitor, the breaker provides circuit-level energy data to help track consumption.

Who It's For

The LB230-GST is aimed at homeowners upgrading to a Leviton Load Center who want integrated safety and smart control at the branch circuit level, particularly for circuits that need GFCI protection. It also suits electricians and contractors installing modern load centers who prefer plug-on breakers that allow rough-in wiring without breakers in place.

It is not the right choice for systems that are not based on the Leviton Load Center architecture, or for buyers seeking a breaker that operates standalone without the required Whole Home Energy Monitor. Those needing a different trip type or ampacity should choose a breaker matching their specific panel and code requirements.

Pros & Cons

Pros

• Integrates with the My Leviton app for scheduling and remote circuit control.
• Provides built-in GFCI protection suitable for both 120/208 and 120/240 VAC branch circuits.
• Plug-on installation enables the load center to be wired at rough-in without breakers installed.
• Delivers circuit-level energy insights when paired with Leviton's Whole Home Energy Monitor.

Cons

• Requires a Leviton Whole Home Energy Monitor to unlock smart functionality, so it is not fully standalone.
• Designed specifically for Leviton Load Centers, limiting cross-brand compatibility.
