Before anybody comments, yes I wired the line side. Tested for the hot wire for line side and wired black wire to black connection on GFCI&nbsp;on line side and white to its side of line. Installed the ground to its screw terminal. Used a GFCI&nbsp;tester. Turned breaker back on at service panel. And the GFCI&nbsp;tester came on says wired correctly. Pushed test button tester shuts off but little green LED&nbsp;light stays on in test mode and reset. Is this a normal operation of these Chinese-made GFCIs?</p> </div><p><a href="http://ecmweb.com/forums/general/general-electrical-talk-discussion/gfci" target="_blank">read more</a></p> http://ecmweb.com/forums/general/general-electrical-talk-discussion/gfci#comments General Electrical Talk Discussion Tue, 20 Sep 2016 00:03:10 +0000 140111 at http://ecmweb.com Thermal Inspection of Electrical Outlets http://ecmweb.com/forums/general/general-electrical-talk-discussion/thermal-inspection-electrical-outlets <div class="node-body forum-body"><p>I was asked if there is a way to check outlets with &quot;thermal imaging to find hot spots.&quot;</p> <p>Can you use a thermal image gun to locate loose/bad connections or outlets that are failing?
