Earth live neutral demo (Each)

This apparatus is an effective demonstration of how the earth wire and fuse
act together to protect both the user and the appliance. The apparatus can be
set up to demonstrate and explain:
• The safe wiring of an appliance
• The danger of an unearthed appliance
• The action of a fuse
In use the appliance is connected correctly and the LEDs in the kettle will
illuminate to show the appliance is working. A fault is then demonstrated by
swapping the live wire from inside the kettle to the case to show either the
fuse melting and protecting the user and appliance, or in the case of no earth
wire, the LEDs illuminate to indicate the passage of current through the
person to ground. The apparatus is clearly labelled and easily allows the
tracing of current from the 'power station' through the 13A socket, plug and
appliance through the live wire and back through the neutral wire. In
addition, the layout of the 3 pin plug is positionally correct to reinforce
the wiring layout and the position of the fuse. The fuse is easily visible and
can be seen to 'blow' when a fault occurs. The unit is supplied with 10 metres
of fuse wire and full instructions (replacement wire is available separately
if required). A 12V DC power supply is required. Connections are made via 4mm
shrouded sockets. Dimensions: 355 x 265 x 540mm
