| 15 A | Lighting and general-purpose branch circuits where the wiring and circuit design permit. | Usually 120 V, single-pole. | A practical choice for monitoring or remotely controlling compatible lighting circuits. | Confirm panel compatibility, wire size, and whether the circuit contains loads that should not be remotely switched. |
| 20 A | Many kitchen, bathroom, laundry, garage, and general-purpose receptacle circuits, subject to applicable code and circuit design. | Usually 120 V, single-pole. | Often the most useful rating for smart monitoring of common 120 V branch circuits. | Check required GFCI or AFCI protection; the smart breaker must provide the protection required for that location and circuit. |
| 30 A | Commonly used for certain electric dryers, water heaters, or other dedicated equipment when specified by the equipment instructions. | Often 240 V, two-pole; some equipment may use a different configuration. | Suitable only when a compatible two-pole smart model is listed for the panel and the specific load. | Verify the appliance nameplate, required conductors, neutral requirements, and any required GFCI protection. |
| 40 A | Some ranges, cooktops, or other dedicated 240 V equipment, depending on the manufacturer’s specifications. | Typically 240 V, two-pole. | A possible choice for a dedicated appliance circuit if the exact smart-breaker model supports this rating and pole configuration. | Do not select a rating from appliance category alone; follow the equipment instructions and verify conductor ampacity and panel listing. |
| 50 A | Some ranges, cooktops, or other higher-load equipment; actual requirements vary by appliance and installation. | Typically 240 V, two-pole. | Consider only when the smart breaker is specifically rated for the load and approved for the panel. | Check terminal and conductor ratings, required protection, and whether the equipment calls for a dedicated circuit. |
| 60 A | Some hardwired equipment, subfeeds, or other dedicated loads when the design and equipment instructions specify this rating. | Typically 240 V, two-pole; confirm the exact circuit configuration. | A specialized option; availability, monitoring features, and panel compatibility may be more limited than for common 15 A or 20 A circuits. | Have a qualified electrician verify the load calculation, conductor sizing, disconnect requirements, and breaker listing. |
