Yes, no problem.
you can't
nothing
No, 120 v is not enough.
No
Yes no problem the transformer should run a little cooler as well.
Yes, using a 220v-60hz microwave in Australia is fine. The voltage of alternating current supplied to homes in Australia is 220v. The frequency of the voltage is 50hz.
More than likely yes it will work just fine.
yes.
No. For more information see the answers to the Related Questions shown below.
No! Normally not, the recistance in the windings is to hig on 60Hz and the pump motor has not power enough to work propelly. This happened to myself when I connected my Whirpool AWE 7519 to 230V 60Hz. Europian model for 50Hz.
Frequency doesn't come into it for normal electrical devices, as long as the voltage matches it will be fine. 50/60hz differences only really affect display equipment.
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
