Mains Electricity - The Three Wires - Do Not Touch.
The UK mains electricity
supply has three wires.
They are called Live, Neutral and Earth
and each wire has its own colour.
Live is Brown, Neutral is
Blue, Earth is Green and
Yellow stripes.
The Live
wire is connected directly to
the generators
of the electricity supply
company.
NEVER touch this wire, it can
kill you!!
The Neutral wire returns
the electricity to the generator
after it has passed through the appliance, to complete
the circuit.
NEVER touch this wire!!
In a complete circuit, it carries
the same electricity as the Live
wire.
The Earth wire usually carries no
electricity,
it is there as a safety
device.
If something in the appliance goes
wrong, or it is wired incorrectly,
then the Earth wire carries
the same electricity as the Live
wire.
To be completely safe, NEVER
touch this wire either!!
