    Continue flipping breakers and labeling them as your helper identifies where the power has been suspended. If your helper cant readily identify a location that the breaker is connected to, mark the area next to the breaker with a piece of tape or a small dot from the marker and come back to it after you have finished identifying the rest of the circuit breakers.
