Figure B.8 Single Point Grounding (2)
The above diagram shows you that a single point grounding system will be a more stable system. If you use thin cable for powering these devices, the end device will actually get lower power. The thin cable will consume the energy.
B.3 Shielding
B.3.1 Cable Shield
