earth gnd
Hi, Is there a perfered method connecting earth gnd to a low voltage power supply and circuit boards?
Normally, I would connect the earth gnd and power supply together at the AC input of the low voltage power supply. I would then connect that gnd to the case.
I would then fan out low voltage power and gnd to the other circuit boards.
It seems the return path for current who source is the 5 volts would be the 5volt ground. The 5v power is derived from ac, who's return path is back to the ac mains using the neutral as the path.
I have recently seen earth ground faned out to each pcb in a parellel fashion.
Is there a benifit to this layout? would this create two gnd loops?
