If the unit draws 30 amps, you need a wire and breaker to handle at least 40
amp. Code is an 85% load actual on a circuit. That 30A breaker will pop
all the time. Sounds like you need to run 8GA and a 40A breaker.

Actually, it's 80%, and that applies only to continuous loads (which is
defined as maximum current for 3 hours or more).

But I agree that if the oven actually draws 30A, it should be on a 40A circuit
with 8gauge wire.

To the OP: If the oven says it needs a 30A circuit, then the 10gauge wire and
30A breaker you have are fine. "Needs a 30A circuit" and "draws 30A" are not
the same. If you don't understand the difference, you should not be attempting
to do this yourself.

Oh, and the guy who said you could use 12gauge wire? He's dead wrong. Don't
let him anywhere near your wiring. And don't take his advice, either, without
checking it out first with someone who actually knows about this stuff -- he
doesn't.
