HO��EHOLD POWER CAbLE� AND PHA�E
Electricity is generally supplied using single-phase and
three-phase systems.
UK: Most homes in the UK use single-phase supplies. In
single-phase supplies, the current flows to and from your
household appliances using a neutral and live wire. The
neutral wire has a voltage close to zero while the live wire
carries a voltage from 20 to 240 volts. The difference
between these two wires makes the current flow through
your appliances.
Europe: Most homes in Europe use three-phase supplies.
In three-phase supplies, current flows to and from a
device through a group of three wires - each one carrying
a fluctuating phase. The three wires, therefore, each need
an individual current sensor which can be purchased
separately.
GETTING �TARTED
LOCATE LIvE O�TGOING ��PPLy CAbLE
The sensor clamp should be fitted over the insulated live
wire. It is recommended that you fit it over the (outgoing)
wire which comes out of the electricity meter located in the
meter box.
This product uses Type C current sensor, do not apply
around or remove from HAZARDOUS LIVE conductors.
Under no circumstances should any force or undue pressure
be applied to any wiring or connections.
WARNING
Care must be taken at all times to avoid
touching or coming into contact with any un-insulated wires
or contacts. If any difficulty with installation is experienced at
all, the advice of a licensed electrician should be sought.
