Note that a dryer consumes 2200 to 2600 Watt : 600 Watt for the motor, 1600 to 2000 Watt for the heater.
At 220 Volt that means 10 - 12 Amps.
At 110 Volt that means 20 - 24 Amps.
However : many dryers have a duty cycle on/off for a couple of seconds.
At switching "in" again there is a short additional "kick-in" motor induction current of 10+ Amps, that together with the normal 20 - 24 Amps adds up to 30+ Amps.
This may just exceed the limit of your 30 Amp fuse.
I suggest to try a fuse (tripswitch) between 32 and 40 Amps, just to accommodate that switch-"in" pulse.
Success! If you need any further advice, just mail me.
