Having a disagreement with some one on "earthing" the out put of a bridge rectifier in a circuit. He has a transformer from the mains, with the secondary going to a bridge rectifier and is then connecting the "negative" of the rectified DC to the chassis of the item. The chassis is also wired to the earth/ground of the mains. He claims that negative is ground so it has to be done. The rectified voltage is ~100VDC.
I always assumed that this was a bad idea. That it would then eliminate the 'galvanic isolation' of the transformer. Neither of us are professionally trained in electronics, so I want a second(or more ) opinion to settle the disagreement.
