You need the ground connected in order to trip with your tester. The faulty wiring showing is probably just the polarity of the wires reversed.

Make sure that they are from the same cable. Electrical Tools Required: Basic Electricians Pouch of Hand Tools, a Voltage Tester and a Multi Meter.
They detect an earth fault by ensuring the current flowing through the live circuit is equal within 30mA of the current on the neutral circuit. First the outer metal sheathing is oily and the individual metal pieces are not good conductors so it would be questionable if you could carry the amps required in an emergency back to the breaker to clip it — the problem is at any given time the ohms the resistance in that outer sheathing might change. See and for details about these devices. Collin, from Grand Rapids, Michigan Thank you for answering my question. Wiring diagrams for 240v hot wires - 9 - how to the last gfci outlet.
Connect the bare ground wire to the green screw. The text is intended as a reference guide to help building owners operate and maintain their home effectively.

You will need to use a in the following locations; The Bathroom, All Kitchen Counter top outlets, All Garages and sheds, Basements and Outside outlets. If the tester lit up, then all you need to do is run a bare copper wire from the ground screw on the outlet and attach it to the metal box. A common problem found in old houses is the presence of ungrounded outlets. Reader Question: several people suggested it would be possible to ground to the box using a grounding screw I was reading your sections on grounding on older home as I am currently in the process of having several two-prong outlets upgraded. But the ground pathway back to the panel in that case is unsafe and unreliable for sat least these reasons: 1.
Both adding a gfci plug into existing non-gfci outlets have 2 prong outlet except that they are designed for a conventional feed-through receptacle. This green screw, sold in hardware stores, fits in a threaded hole in the back of the box. If not, would a whole home surge protector at the box take care of the problem?

Ground-Fault circuit-interrupter, the ground wire, you may not match what. Surge protectors help protect your equipment from surges by clamping the voltage to a specific value. Estimated Time: Depends on personal level experience, ability to work with tools, work with electrical wiring, and the available access to the project area.

Background: Donald, a Handyman from Lackawanna, New York. Electrical troubleshooting will be required to find the problem so it may be corrected to prevent the tripping circuit breaker. That might make for a good future blog post. Back to the original comment: The small thin wire is considered a bonding of the raceway to the system. Even if a homeowner knew 100% that they had bonded cable, and that it was a low resistance ground back to the box, there are enough questions that I would not feel comfortable advocating this method on my website.
Some testers apply up to 30mA of test current; so using one of these while touching a metal cover plate could result in an uncomfortable and possibly dangerous shock. Connect a green jumper wire which you can buy with a screw already mounted in it at hardware stores from the green grounding nut on the new receptacle to the box. The first problem is that you may be using the wrong cable and breakers. This would be safer than either method explained in the post.
