Dryer wiring at the FUSE panel - correct way?

How should the FUSE panel be wired for a clothes dryer?

Clothes dryers use 110v (for timer, buzzer, etc.) and 240v (heating
element). So it has two hots (red and black) running to the dryer plug.

But at the FUSE panel, should it be two separate 20-amp fuses, or two
separate 30-amp fuses? Or should the dryer have a special double-fuse such
as a cartridge type fuse that is 30-amp?

I realize if this were a breaker panel it would just be a double 30 - but
how about with a FUSE panel?

I would have run two separate 20-amp fuses, but I was informed this is
incorrect and it should be 2x 30-amp fuses, and that it would be in series.

Can it be wired to 2x fuses, or must it be to a single cartridge type fuse?

Thanks,

Terry

You should use 30 amp fuses and opposite phases in the panel, and at least
10# copper wire. Larger if the dryer is over 50 feet away from the panel
measured by wire run. Since you have fuse protection I would consider
installing a simple 30 amp circuit breaker in a enclosure at the dryer. Then
you would be assured that if something happens it will trip the breaker.
Other wise you could blow one fuse and have the dryer tumbling and no heat.
Your significant other comes out and is mad as hell because the clothes are
still wet. I had a energy management system that would dump the heater when
the load on the home rose beyond a set point. The misses and I had lots of
arguments about this.

Just my view from the cheap seats
