<p>[quote user="7j43k"]</p> <div class="quote-header"> </div> <blockquote class="quote"> <div class="quote-user">rrinker</div> <div class="quote-content"> <p>...connecting the low voltage side of the system directly to earth ground means in the event of a wiring fault, you could be putting mains potential on the rails.</p> <p> </p> <div style="clear:both;"> </div> <p> </p> </div> </blockquote> <div class="quote-footer"> </div> <p> </p> <p> </p> <p>I'm not following this. Please give an example of such a wiring fault. And please explain how that would put "mains potential on the rails" (120V). And please explain how NOT grounding the low voltage side would preclude putting "mains potential on the rails".</p> <p> </p> <p>Thanks,</p> <p> </p> <p>Ed</p> <div style="clear:both;"> </div> <p>[/quote]</p> <p>I would venture to guess any other device connected to 120VAC in your home with an electrical fault that results in 120VAC in places other than where it should be.</p>
