Convection oven tripping breaker...Newmar 07 KSDP GE Profile Convection Oven

It's happened twice now this week. As I research this I see that Microwave Convection ovens draw 12.4 amps? The circuit breaker it trips is 15 amp.

A YouTube electrician says that breakers will tolerate the rated load temporarily, continually they will tolerate 80% of the rating. That would be 12 amps, no wonder it trips the breaker, if it is drawing 12.4.

So, I am asking myself, why would the Convection circuit no have a 20 amp breaker. It seems that several other outlets are on this circuit.

The breaker is a double breaker, one switch is 15 the other 20.

Anyone think I have a problem with the oven?

Why not upgrade it to a 20/20 breaker? Anyone think Newmar would use two different gages of wire?

Lots of Newmar rigs out there, what is happening to me that is different from others?

To upgrade the breaker you need to confirm you have 12 gauge wire.

If not, you could overheat the 14 gauge, normally used in 15 amp circuits.
