Actually, the other fuse will blow, too, because the load will be more than 15 amps and will try to draw all of it from that second circuit.
Also, don’t EVER replace a 15 amp fuse with a 30 amp fuse!
Those fuses are rated for the WIRE, not the LOAD.
I totally agree with Najataagihe as a fuse is in line to protect the wire and not the equipment tied on to the wire. To use a 30 amp fuse you would have to upsize the wire to the proper wire gauge.
