Gfci tester open hot

In the illustration above, the left-hand scenario shows the bad connection being at outlet B, which is the outlet that reads open hot . The right-hand one shows the bad connection being at . There are two matters important to finding the bad connection. One is whether the hot or the neutral is open. The other is the extent of the outage compared to the extent of that circuit.

Master electrician shows chart of the many readings that outlet testers may give, explaining what they mean and how they can sometimes be misleading.

Had an interesting thing at this mornings inspection. However all three lights in my little tester were blank. Typically this means that there is no power at the outlet. I looked at the label on the tester and it indicated open . Problem is, the outlet is not working, GFCI receptacle tester is showing open hot . My non-contact voltage tester shows the line coming into the outlet is hot , and the line going to the adjacent outlet is also hot.

I replaced the gfci outlet, and same issue. That reading is the one that will often show up when the actual condition is the more common one called open neutral. This master electrician only explains why on his website, not here.

Common problems of GFCI being hooked up wrong. Electrical contractors and inspectors have relied on receptacle testers for checking electrical wiring at an outlet for many years. Assuming all is properly grounded the tester is capable of indicating an open neutral. I would first confirm that an open neutral condition exist before you go any farther, and then . The tester will correctly diagnose most of these things: Open Hot : the black wire is present in the box but disconnected from the plug (or otherwise not making good contact).

An NCVT can still light up if . GFI -protection, and functionality of plug-in receptacles in homes. If the tester is correct, this means the receptacle is dead from the hot wire (usually black) not actually being hot. Receptacle testers can also be used to identify live circuits, determine the ground leg .
