The total current (in amps) for all loads connected to a given breaker cannot exceed 85% of the rating on that breaker; if it exceeds this level, then the number of breakers or fuses should be increased accordingly. Hello, I'm Sam. a circuit will cause more heat to be generated in the wires. If your lights start to dim or flicker while using a small wire, this is another sign that the current is too much to be carried by such wires.
