Yes, if you rewire the bed and rewire the plug on the wall to 220 volts.
No, a device designed for 110v will not work on 220v without a voltage converter.
No, a device designed for 110v cannot work on 220v without a voltage converter.
Yes, although you might have lucked out and tripped the breaker first.
Either. Motor size or your available power local to the pump installation are the determining factors. If you have to use a large motor, 220v requires less amp draw on the circuit and allows a smaller wire than a large motor running 110v. If 110v is already there and you only need a small motor, run 110v.
To convert 110v to 220v using a step-up transformer, connect the 110v input to the primary winding and the 220v output to the secondary winding of the transformer. The transformer will increase the voltage while maintaining the power output.
No
No.
At 20 amps the 220V will supply twice (2x) the power that the 110V will supply. The answer depends upon your meaning of the term 'better'. If you have a specific size load that you are supplying such as a motor that will accept either 220V or 110V then by using 220V you will have less of an impact from voltage drop and the conductor size will be smaller due to the current being 1/2 of the 110V. If by better you mean which one will give you the most power then the obvious answer is 220V.
NO dear we can not rotate a 110 vlolt motor on 220,but if your voltage is 110v then y can rotate it on 50hz ,no problem,but it will rotate at lower speed, ENGR. NASEER AHMED,PAKISTAN
220v and 110v are almost the only voltages used around the world because they are the most efficient.
The breaker will blow because you are effectively causing a short circuit.
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.
