Double pole breaker?

According to install manual, a DOUBLE pole fuse/breaker is required on the AC input to a 12/2000 multiplus in a 30 amp circuit. Is this correct? Or could I use an inline fuse?

IMO it is highly recommended to use a double-pole circuit breaker.
If you have two hot wires (2x120V) and there's a problem on one of them, the double-pole circuit breaker shuts down BOTH wires. That does not happen, when you fuse each of the wires independently.

@Davis Kyle, you need a double-pole breaker for your "shore power" input; a fuse is not appropriate.
