How can i convert our 220 volts wall outlet to 110 volts for a microwave oven.

have it inspectied my a real company . if it was wired wrong, such as the oven was 220 volts and the microwave was 110 volt they tried to split the 220 down to 110 and wired it wrong. my question is was there a oven there before, if not did they run new wires for that oven . 220 volt needs 4 wires to run it , to be right. It sounds like 220 was put to the microwave.

A device which is designed for 110 volts MUST NEVER be used into a 220 volt outlet. This can damage the unit and make the motor winding burnt.
You need to buy a STEP DOWN TRANSFORMER with a good rating (220volt to 110 volt) so that the unit works perfectly without damaging the motor.

If your microwave is wired for 220 volts AC and your country standard house current is 220, and the plug is of the proper configuration, plug it in.

Standard microwave size is around 1100 watts at 110 volts Normally, two times the voltage is 1/2 the wattage. Ohms law, Voltares Law and Watts Law apply.

If your microwave is 1100 watts at 110 volts --- yes you will need a step- down transformer of some type.

Do I understand you plugged this device into 220 Volts? Is this a machine designed for 110 Volts? Check the fuse - if it is burned out (as I suspect it will be) replace it. If the machine comes on - check out its operation. If it does not come on - I think that is the end of the road for your machine. To get to the fuse, remove the cover. Find the fuse near where the cord enters the cabinet.

I don't know where you live (please do not say) nor what the prevailing standard house hold voltage is. I don't know where you got the oven and please don't say. I really don't understand how you accidentally plugged a 110 Volt machine into a 220 volt outlet - that would be interesting to hear about.

It depends on if you are running a 220 or 110 volt supply. Assuming that your supply is 110 volt and your microwave draws about 2000 watts, that would mean that you need a wire with a cross section of about 2.5 sq, mm to allow a safety margin. If your mains are 220 volts you can use 2 sq mm or a little less - say 1.5 sq mm to be on the safe side. (On 220 volts a microwave draws aprox. 2 amps for every 200 wats output and 1 sq mm wire can carry 10 amps - as a rule of thumb. At 110 volts these figures are roughly double).

At 110 volts 700 watts equates to 6.4 amps, at 220 volts is is 3.2 amps - no problem!

Hi,

All the possible problems will mean removing that thing...it is likely that a fuse inside blew, but that may be a sign of bigger problems...

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

no,not an inexpensive alternative

Ah, the problem of the ages. There are 2 solutions. One is a transformer of the proper size, and the second is to purchase a heavy duty battery charger (that runs on 220 volts). Connect the red and black (+ and -) wires to a 12v to 110v voltage inverter, similar to what you would plug into a 12v auto 'cigarette lighter' socket to produce 110v current from a car battery. The charger turns the 220 vac to 12 vdc, and the inverter turns the 12 vdc into 110 vac. This works, as it is what I did when I moved from the US to England.

I don't see what range you're referencing. I see a title of microwave ovens. But, in any event, here's circuit requirement for each.

If it's a cooktop range: 220 volt 30 amp dedicated circuit

If it's a microwave: 110 volt 15 amp dedicated circuit
