Some time ago some one asked a question about hooking a bridge rectifier uip to the line voltage rather than the secondary of a transformer. They were informed that such an arrangement would not even be discussed. What is the reason for this position?

Can you reference that post.

I'll try to find it. I'm sorry I'm not having any luck It was in 2011 I believe.

So what is your question on the subject. Keep in mind that this is an Electric and Lighting board not the Electronics board (there is an Electronics board on AMHD however). Perhaps that was the reason, but such response would be unusual. It would be more normal to just refer the poster to the Electronics board.

If you had or were going to use a bridge rectifier it would be important to know what the maximum rated input voltage and current was...
Line voltage could be 120V... a rectifier that operates at this level would not be inexpensive...

The last time I did anything with a bridge rectifier it was maybe 10Vdc and a few milliamps...

Is there a more specific question?

You can use a bridge/diodes for rectifying any voltage they are rated for. Check the specs.

Some rectifiers and specs, can use a full wave bridge or 4 diodes:

Pretty common to go from 120 VAC to DC for yard blowers and similar.

Maybe that was where I saw the post. I've searched the electrical and lighting posts back to 2009 with no luck. If my memory serves me, it gave the impression that it was a safety issue.
