Absolutely not. A radiation overload(as in too much radiation) is unlikely as the inside microwave couldn't possibly be on.
The metal parts in the smaller microwave, like any metal, would send a "feedback pulse" (a reflection) through the larger microwave, causing a massive increase in the amount of heat and current running through it. Once the ground plug rejects the extra current, the larger microwave will ignite.
Warning: If you have done it already and if you don't see a fire, you need to be cautious and keep an eye on it.
No the metal of the smaller microwave would sparke start a fire and bur your house down!!! Its common sense!!
Probably end up with a fire and a mess of expensive scrap metal in the kitchen.
Kaboom
Radiation overload. Dont do this.
highly dangerous dont attempt it
I got a microwave for Christmas, and it is way smaller than the one in my kitchen. If I try to microwave the smaller microwave, will it like super charge the smaller one?
