I learned a really good way to trace out breakers with-out a tracer very early on.
Use an Ammeter, and amp out all the breakers, and write down all the values. Then go plug in a 500 - 1000W flood light in it. Check again. (If it didn't trip already.) Big number change is your breaker.
That switch on a rope idea is flirting with disaster.
