Electrical Wiring in the Home/Fan pops fuse when turned off


Hi Bob, I just put in a new ceiling fan and light where an old light was.  when i turn the fan and lights on, by the switch on the wall  it works, but, when I turn it off by the wall switch it pops a 30 amp fuse. Any suggestions? By the way my house was built in 1950, and I also have two cirrcuit boxes as well.
I'm a electrician illiterate. :(

The fuse should not be a 30 amp fuse.  That is a fire waiting to happen.  If you are not sure of the gauge of the wire, put a 15 amp fuse.  If you can tell that the wire is 12 gauge throughout the circuit, then put a 20 amp fuse.

Did you change the wiring?  Are you sure that the fan isn't running when the switch is off, but the fuse pops when the switch is turned on?  In that case the white wire from the switch needs to go to the black wire of the fan. The white wire from the switch is a hot wire.

Check all of the wiring, and make sure no bares wires are touching anything.
