If your monitor is already installed, skip to step 11.
In the panel where you placed your Sense monitor, find the monitor power cable connected to the top port of the Sense monitor. Connect the black wire and the red wire to an empty 240V breaker and the white wire to the neutral bus bar. Sense draws less than 0.1A, so you should use the smallest 240V breaker available for your main panel.
Don’t have an empty breaker?
Connect to an existing or add a new 240V breaker. Do not use a tandem breaker, unless it is 240V. Learn more.
