Swap wires for oven and cooktop
Hi,
I got a new wall oven and realized that my current circuit is too small. The old oven ran on a 10 AWG 30 amp, and the new one requires 8 AWG 40 amp.
My cook top I believe requires only 30 amps and is currently on a 40 amp circuit using 6 AWG aluminum. Neither of the wires for the cook top or oven have enough slack to reach the other so I will need junction boxes.
What wire should I use to go from the 6 AWG to the junction box where the factory oven will connect? I have some 8 AWG copper romex lying around, can I use that since it is equivalent to 6 AWG aluminum?
What should I use to splice the copper and aluminum together?
Drawing attached is what I would like to do. Also, I already tried to run a new wire and when I started drilling the hole from the oven area to the basement I found out there is duct work, so no easy way to get wires down there...
Oven is 8.4 KW at 240v
Cook top is 6.4 kw at 240 v
Thanks in advance!!

Are the appliances 240V or 120/240V?
The connectors to safely connect the copper to aluminum will probably cost more than just installing a new oven circuit. Do you have attic, crawl or basement access?
