Markies, Thats INDEED a "Weird" system of any branch circuit and is certainly NOT how I would have designed it let alone potential NEC violations !!!!!!!!!!

I will try n address your questions:

Q What are the reasons for this?
A Cuz its one screwed up wiring plannnnnn

Q Shoudl I have something rewired?
A YESSSSSSSS by a qualified licensed electrician

Q What are the consequences of going to a 15 amp breaker and removing the 10 amp?
A If the branch circuit wiring is all at least
14 Gauge yes you can install a 15 amp breaker and if its 12 gauge then a 20 amp breaker (More typical household branch circuit wiring)

Q Breaker will trip after 2-3 minutes of run time.
What are the reasons for this?
A CUZ ITS DOING ITS JOB AND PREVENTING AN OVERLOAD N OVERHEATING WHICH COULD BURN YOUR HOUSE DOWN...... A Thermal magnetic breaker senses a continued high current n is designed to trip out exactly how its doing.

Q If a breaker trips 50 times, do they get weak?
A Its possible cuz they arent really designed to serve as switches with lots of use although they should be excecised now n then

Heres the deal n why it trips: If the breaker is a 10 amp, the maximum continuous constant current draw allowed on that branch circuit is only 8 amps and that computes to only 960 watts of a continuous load. Once you start pulling 10 amps or so for too long the thermal is gonna heat up !!!!!!

John T Long Retired electrical design engineer so a lil rusty on the NEC buttttttt not so rusty that I dont recognize what you have as a wierd system to say the least.....

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point ... [Read Article]
