Differance between power circuit and control circuit

Answer Posted / b. salazar

The power circuit is the circuit that begins at the disconnect, travels through the controller to the machine. The control circuit could be a lower voltage which goes to the switches and relays which determine the order that the machine operates. The control circuit provides power to the controller and when the contacts close, connects the power circuit to the machine and turns it on or off.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
