I was jsut quoting my physics teacher. I never actually checked that (we have a gas range at home, way cheaper and more effective).
Must be that way then.
I've once seen an electric range connected via simple red-grey CEE plug and receptacle at acountry fair.
Was a nice thing. They tapped off the OH service of the nearest house and ran OH cable over some trees to the big tent. One support was a long board they bound to the lavatory trailer with some insulated copper wire. They drove 2 drywall screws into the top of the board facing upwards, laid the cable between and fastened it with some wire. From the main panel they ran literally kilometers of extension cord. (Was a tent for several thousand people). I saw that work while doing some minor helper-jobs (mostly standing around and cheering up people)
