Replacing appliances i have a 220 that was used to plug in a one piece stove oven ,,, now im going back with a two piece flat top stove and a slide in oven, ( seperate) they have wires no plugs, how do i make this work

Bodyman,
I have wired lots of things in the home myself.
I will need to be very sure what you have and want.
First lets see if the circuit can handle both of them at the same time.
See if you can find the amp ratings of the two new things that is your max current needed. On the flipside you can see what the fuse or breaker is on the supply side. Its possible that since you had a one piece item that did both things that you might have enough. I suspect the issue is that you will need a way to turn the one 220VAC outlet into a system that will connect to two appliances. It is good to be able to unplug things to work on them and replace them. This is probably going to require a box of some kind to join them all into one cable that plugs into the assumed 220 VAC socket you have. If there is a way to send me digital photos of the labels on the appliances you are going to install and the one that took out that show the Amps and Volts as well as the plug that is in the hole in your kitchen that would help. If you are pretty sure what you are reading then just listing them would be fine. If there is not enough supply volts and amps then this is a much bigger electrical job than I would suggest you do to make it safe and right.
