Re: Grounding Issue

Here is clarification for you on what i'm actually doing.
I have a cold cathode light that runs off 120VAC, i have a inverter that
converts 12VDC to the neccessary 120VAC.. i have an series of LED's that
need DC.. so i was thinking of running the positive line for the DC power to
the LED's then just hook the ground of the LED segment to the same ground as
the return to the inverter.

Can the below be done safely? I have two circuits running 2 different
sources.. space is limited and if I can get away with using a single
ground
that would be fantastic.

+120VAC-----------------|+ AC
-----------------| LOAD
|
GND------|
|
-----------------|-DC
+12VDC-------------------|+ LOAD



I presume a bridge rectifier?

The answer is no... sparks will fly... you will be injured... don't do
it.

I love to cook with wine. Sometimes I even put it in the food.
