Quick answer
No. StopWatt is plug-in only and requires no changes to your wiring or panel.
Before you start
- Confirm your outlets are standard grounded household outlets (90V–250V).
- Unbox and inspect each unit for shipping damage.
- Decide placement using the room map below.
Installation steps
- 1. Plug the unit directly into a wall outlet — never a power strip, surge bar or extension cord.
- 2. Wait for the indicator light to illuminate, confirming the unit is powered.
- 3. Leave the unit plugged in continuously.
- 4. Repeat for each unit in your bundle, spacing them across floors and circuits.
Recommended placement by home size
| Home size | Units | Suggested placement |

| Under 1,200 sq ft | 1 | Central outlet, ideally near the kitchen or HVAC circuit |
| 1,200–1,500 sq ft | 2 | One per floor, one near the largest motor load |
| 1,500+ sq ft | 3 | One per floor plus one near the panel, garage or utility room |
Safety rules
- Keep the unit dry and away from heat sources.
