When I went to replace the two 3-way switches I noticed that there were not two travelers but only one. I located the hot wire, and a brown wire connected&nbsp;to the traveler terminal. This brown wire is connected&nbsp;to one traveler post, then the same wire without being cut runs to the second traveler post. I have never seen this and always thought you had to have both travelers for the 3-way lighting to work. Why would this be like this and how does it still work?</p> <p>&nbsp;</p> </div><p><a href="http://ecmweb.com/forums/electrical-101/questions-help-rookies/3-way-switch-traveler" target="_blank">read more</a></p> http://ecmweb.com/forums/electrical-101/questions-help-rookies/3-way-switch-traveler#comments Questions & Help for Rookies Thu, 17 Nov 2016 02:26:44 +0000 142521 at http://ecmweb.com New Ground Fault System with an Untracable Fault http://ecmweb.com/forums/electrical-101/questions-help-rookies/new-ground-fault-system-untracable-fault <div class="node-body forum-body"><p>Hello All,</p> </div><p><a href="http://ecmweb.com/forums/electrical-101/questions-help-rookies/new-ground-fault-system-untracable-fault" target="_blank">read more</a></p> http://ecmweb.com/forums/electrical-101/questions-help-rookies/new-ground-fault-system-untracable-fault#comments Questions & Help for Rookies Fri, 04 Nov 2016 18:49:24 +0000 142151 at http://ecmweb.com Safe or Not Safe? Mailbox Lamp http://ecmweb.com/forums/electrical-101/questions-help-rookies/safe-or-not-safe-mailbox-lamp <div class="node-body forum-body"><p>I&#39;m replacing a mailbox lamp for a friend. I&#39;m getting 120V&nbsp;across the black and bare. I get no voltage across black and white. I&#39;m assuming that the neutral is broken, probably underground. An electrician estimated $500 to dig a trench and replace the cable from house to mailbox. He couldn&#39;t advise me (for liability reasons) when I asked if black to bare would pose any safety hazards. So I&#39;m researching for the answer. I was thinking that I would wire it that way, making sure that the breaker controlling it was GFI protected.</p> </div><p><a href="http://ecmweb.com/forums/electrical-101/questions-help-rookies/safe-or-not-safe-mailbox-lamp" target="_blank">read more</a></p> http://ecmweb.com/forums/electrical-101/questions-help-rookies/safe-or-not-safe-mailbox-lamp#comments Questions & Help for Rookies Thu, 03 Nov 2016 18:55:51 +0000 142091 at http://ecmweb.com Light Switch Voltage is Only 75VAC http://ecmweb.com/forums/electrical-101/questions-help-rookies/light-switch-voltage-only-75vac <div class="node-body forum-body"><p>The overhead light in the master bath closet of a 25 year old home stopped working.
