Hello everyone. I am new to the forum and I need some advice to run 1 50 amp extension cord to one of my room and 1 30 amp extension cord to my other room.

The first room:
Since I have an electric stove and I don't plan to use it. I am thinking about plugging the 20-30 feet 50 amp extension cord in the electric stove outlet. I check the breaker and it does say 50 amp. Then, I going to plug a 50 amp timer box in the extension cord.

The second room:
Basically the same setup except this is going to be a 30 amp extension cord from the washer and dryer, don't need to use it, and plug it in a 30 amp timer box.

Here is a picture of the 50 amp timer box: http://www.garden.com/item/50-amp-ti...digital-timer/

My questions are: Is it safe? Is this setup doable? Does the extension cord have to be in a straight line or can I mount it on every ceiling wall corner running it to room 1 and 2. Please give me some advices. Thanks!
