I just back from a call from a gentleman about his wall oven not heating properly.

I found that the 240v oven was wired on a 120v circuit.

1. The nameplate reads 3.4 Kw--I see it as #12 on a 20amp DP( 210.19(B)), 2005
2. The manual reads to install on a 30amp DP #8.

Which would you use 1 or 2? Or would you go with #10 on 30amp, future use.
 
I would install as the manual specifies. The #8 would allow for 40a for future use.

You can always install a breaker lower than the conductors are rated.
