The Efergy Additional Sensor is used in conjunction with the Elite or E2 Energy monitor if you have a three phase supply or your cables are a non standard size.
The Efergy Elite and E2 are supplied with one sensor, which will work with most standard domestic supplies. If you are going to use your Efergy to monitor a three phase (industrial) supply, you will need two additional sensors. You can also use this sensor for larger supply cables.
The sensor is attached around the live cable that comes from your electricity meter, this will usually be in the meter cupboard.
Allows you to monitor three phase power.
