No the camera should not be plugged into the same electricity supply as any other equipment used to provide sound for the recording.
A mains loop is where there is an electrical connection shared by two bits of kit, you complete the loop by connecting the SUB to the camera audio input. By running the camera on battery and not supplying it with mains power, you break the loop and the noise will not be generated.
