Introduction
The ground or earth refers to the reference point in an
electrical circuit from which voltages are measured,
a common return path for electric current, or a
direct physical connection to Earth. Electrical circuits
may be connected to ground or earth to prevent
user contact with dangerous voltage if the electrical
insulation fails.
Earth points can be useful when tracing electrical
faults typically when several electrical devices are
malfunctioning.
