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 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 120 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 STARTED

LOCATE LIVE OUTGOING SUPPLY 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.
