Powersensor works by detecting the electrical supply to your home. Your home's electricity is supplied entirely through your service fuse. It is the easiest way to install the sensor and provides a strong signal for monitoring your energy consumption.
Do not mount the sensor directly on the service fuse. Your electricity provider may need access to it so attach the sensor next to the fuse. See the below examples of Powersensor service fuse installations.
Always attach your sensor next to, not on your service fuse.
