Fitting the sensor
Step 8 - Find your electricity meter
Your meter is normally on an outside wall, in the garage, basement, utility room, or in
an outside meter cabinet. Apartments and flats may have meters in communal areas
with safety panels to protect the wires entering the meter. In this situation contact
the technical support line for advice before attempting to install your npower
electricity monitor.
Step 9 - Identify cable 4 on your meter
Most homes in the UK have a single tariff or dual tariff meter.
A single tariff meter has four cables exiting the meter. In some cases the cables
(especially cables 1 and 2) may be tied or encased to prevent tampering.
A dual tariff meter commonly has 5 cables exiting the meter, including an auxiliary cable
running between cable 3 and cable 4. This is smaller in diameter than the other cables,
and runs into an adjoining metering device.
Identify cable 4, the live cable exiting from the meter to the fuse box or main switch. The
live cable is usually located on the far right of the meter and could be red, brown or grey
in colour. It could also be identified with a red or brown label and/or have a letter L on it.
The sensor is best located on the live cable coming from the meter. If you are unsure
which this is you can try a number of cables and check the display for readings each time.
The display will need to be paired to the transmitter before you will see any readings.

how to identify the cable on your meter.
