Disconnect the main switch, and determine the size of the wires in each circuit. Don't include the insulation in your measurement.
BE CAREFUL!
Even though you have disconnected the main switch, the wires coming into it are still "live". So, do not touch any wires. Instead hold the wire size chart near them so that you can tell which gauge each one is.
Write in the proper size fuse for each circuit on your chart.
Replace Any Wrong-Size Fuses
Do the fuse sizes you have written on your chart agree with the ones that are in place in the panel?
Get the right size fuses and replace any that are wrong. Make sure that you have a reserve supply of the right sizes, and that they are handy for future use.
Talk it Over With Your Parents
Do you think that your home has enough of the proper size circuits? If not, talk it over with your parents. They may want to ask an electrician to go over the wiring and make the necessary changes.
