Not everyone uses the same codes.

So that could be racist!

Yea my suggestion is to get a licence.. He says he switched the poles. Main lines coming into the building? I do not think he will live long enough to call an electrician. He will electrocute himself first.

Since this oven will be on for more than 3 hours, shouldn't it be #8 wire with a 50 amp breaker?

The heating element probably cycles on and off.

you need to replace the cable to the oven with a bigger one,
As the current one is NOT up to the task,
And if it has been constantly over loaded ?
Is probably now damaged.

All this is assuming your main panel/general service
can handle the extra load
Which we don't know for sure

You have to consider the other loads on that leg.
If you had an amp meter, you might discover your handiman put most of the lighting load on one leg.
Just my guess due to you only mentioning one load.
That # 10 or really rated for 40 amps but we usually fuse them at 30 with some very specific exceptions. I'm not seeing that as the main problem.

Heat could be an overload or a poor connection. If a wire burns, it always burns towards the source.

One more thing before this thread gets closed.
How do you know the oven draws 37.5 amps?
Are you looking at a name plate?
Do you know the voltage coming into the building?
208 or 240?

An engineer would give you a correct answer but like Hack's completely useless for the intent of the question asked.

And the fact that some locations don't require them.
