We have a built in microwave in our caravan of about the same wattage and we find it generally works on a 6 amp supply in France. In the UK most sites have 10/16 amp supply.

watts divided by the volts - 700 divided by 230 gives you a draw of 3.04 amps.  Provided that your hook up has more than that available then the only thing that will happen is that your custard will be done in about a minute.

Leave the plate in when you travel and that could do more damage than the electrics!!!

It is a common mistake made with M/waves the 700W rating is the heat output, the actual rating in electricity is considerably more,I have a 900W M/wave in my van but it actally draws in excess of 7amps.

The wattage referred to re a M/wave is microwave power and as such the conversion chart doesn't apply.

A M/wave is app 60% efficient,a700W microwave oven consumes app 1100 W of electricity to produce 700 W of microwave power.. The other 400 W are dissipated as heat, in the magnetron tube and operating,transformer,turntable motor,fan,light and the electronics.

It should be considered when on low Amp sites
