Why do you need two fuses for a single-phase motor?

** Cos the AC supply is two phase.

The OP is an American.

They have spit phase power where 240VAC is split into a pair of 120V lines
with a common neutral.

While 120V appliances use one or the other, some ( usually high powered )
ones are rated at 220 /240 and connect across the pair.
