if I have a device that uses 110 25 AMPs, but I don’t have a 30AMP circuit, if I split the load across (2) 15AMP circuits, what would happen?

Question

So let’s say a house has 150 AMP service, and there were two dedicated 15 AMP breakers dedicated to this device, does the current split evenly, to work like 30AMPs, or would it trip at 15 AMPs?
This is a theoretical question, I assume code would be against this anyway, and I would not do it, but would it work?

One thing to remember is that a 15A breaker doesn’t trip at 15A. Not entirely sure on the US graphs but it likely doesn’t trip until 21A and even then it may be up to 10,000 seconds before it does. Instant trip tends to be 3-5 times the rating.
