circuit fuses to blow or circuit breakers to trip. In some
cases, incorrect sizes of fuses or circuit breakers were
used and the wires overheated and burned off the
insulation. This condition can cause shorts and grounds
that become potential fire or electrocution hazards.
Furthermore, some malfunctions can only be detected
by visual examination of the finished product. These
