last wire to be pulled away if the mains cable should accidentally be pulled, and will
thus guarantee the ground connection. Do not use gas pipes to ground electrical
appliances.
A wiring error, as well as impeding the correct operation of the appliance, could also
damage the electrical apparatus that it contains.
