UK Mains Electricity - How to wire a 3-pin Plug.
The three wires are contained in a plastic outer covering
(called the flex)
which acts as insulation.
The outer covering is held inside the
plug by a flex grip.
Each wire has its own coloured insulation, to
show if it is Live, Neutral or Earth (see previous page).
The wire inside is made of copper,
which is an
excellent conductor. The copper wire is
held
inside the
brass pin of the plug by a small
screw.
The Live wire is always
connected
to the Live pin of the
plug by a fuse.
