HOUSEHOLD POWER CABLES AND PHASE
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 ows 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 120 to 240 volts. The difference
between these two wires makes the current ow through
your appliances.
Europe: Most homes in Europe use three-phase supplies.
In three-phase supplies, current ows to and from a
device through a group of three wires - each one carrying
a uctuating phase. The three wires, therefore, each need
an individual current sensor which can be purchased
separately.
