Fuse Simulation (C) J.P.Taylor Help Text
============================== =========
A fuse is a safety device to stop too much electricity flowing through a cable
or appliance. It is important to choose the correct fuse. If the fuse is too
small it will blow (melt) immediately. If the fuse is too big you risk too much
electricity flowing if there is a surge of power, in which case your appliance
could be damaged, or more seriously, the cables get hot and a fire could start.
This application has a range of appliances you can choose from. Click on one
of them with the left hand mouse button and the details will be entered into the
simulation section in the top right corner. You then have to choose a fuse to
insert into the circuit. Click on one from the selection in the fuse section.
To help you out, there is also a calculation section which calculates the
current drawn by the appliance. The fuse you choose should be the next size up
from this value.
NOTE: Although only a picture of a plug is used, fuses greater than 13 amps are
only used in a distribution board, NOT IN THE PLUG ITSELF.
When you have chosen an appliance and a fuse for it, click on the "Switch on"
icon and see what happens. If you have made a mistake, just choose a new fuse
and try again. There is no need to reset unless you want everything cleared to
start again.
