The fourth prong grounds the body of the appliance. You can attach it to the frame or simply ignore it.
440V equipment cannot operate directly on 220V. You would need a step-up transformer to increase the voltage from 220V to 440V for the equipment to function properly. Attempting to power 440V equipment with 220V without the proper transformer can damage the equipment and pose a safety risk.
high voltage pass 220v instead of 110 to xerox 7335 machine
The amount of amperage needed for a 220V well will depend on the wattage of the well pump. To calculate the amperage, divide the wattage of the pump by the voltage (220V) to get the amperage required.
For 220v circuits
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.
condensation
bum chum
are you changeing to gas or propane? that would be the only reason to be changeing one. It will be on the end of your line for your main burner
you can't
UK is 220v
Yes, no problem.
nothing
Yes if its a big difference.
changeing ignition barral
becase it constly changeing
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
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.
