Can we use common Electrical ground for both instrument and electrical. IF yes why..

Answer / bijnan debnath

Electrical appliances such as motors, welding machines etc
should be grounded separately. Separate and electrically
isolated groundings or earthins should be provided to the
instrument. Because Electrical appliances may generate
noises during may operation which may affect the proper
functioning of the instruments.
