Learn Home Electrical Troubleshooting and Repairs, Licensed Electrician Reveals the Secrets of Successful Electrical Troubleshooting Methods used to solve the majority of the home electrical problems and wiring failures encountered. The electrical system voltage information may be identified by observing the equipment label on the electrical breaker panel which is supplying the outlet circuit power. This is an older home which was upgraded with a significant expansion and electrical circuits that were joined together in a manner driven by the convenience of a circuit being nearby as opposed to other factors that might appear more logical, such as putting all kitchen outlets together. Replaced circuit breaker no change, moved circuit breaker to a new location on the bus, no change. Root issue: My switch is passing 50v DC onto the line when in the off position. When measuring these Outlets I get 120 volts from live to ground, I get 0 volts from neutral to ground, but the weird thing is I get 0 volts from live to neutral when I should be getting 120 volts correct? On a 120 outlet while fa. This might fix your issue. Since you said that the nearest receptacle is at 120V, I'm assuming that it's on the same circuit and the next wired in sequence? The ground is connected through. I get 30 volts when measuring neutral to ground, I get 60 volts when I measure neutral to live, and I get 120 volts when I measure from live to ground. Be sure to make a good splice and use the correct size wire connectors approved for the number of wires, and the gauge of the wires. youll find a ton of information. The outlet appears to have 3 wires, I'm guessing the neutral, the ground and the hot wire. Thanks again guys, its semi-embarrassing to not understand this stuff. The light goes off if I pull the air gap so it is definitely the switch.

Reddit and its partners use cookies and similar technologies to provide you with a better experience. Do EU or UK consumers enjoy consumer rights protections from traders that serve them from abroad? Even if somehow the voltage was emanating at the receptacle, #14 or #12 wire over a short run doesnt have anywhere near enough resistance to bleed off 30 V. This makes me wonder if you are seeing induced voltage. Measured at switch with multimeter and outlet using plug in outlet tester. I know the new light fixture works. If neutral-ground voltage is 0 V - again assuming that there is load on the circuit - then check for a neutral-ground connection in the receptacle, whether accidental or intentional. How to fix low voltage on one or more of your outlets. Attaching the Wires to the Outlet. While I'm not an electrician, I've done a ton of wiring in my house, including bring 30A electricity to my tool shed and wiring the outlets and lights myself. If the reading is zero, then the breaker is faulty and need to be replaced. Major factors that go into voltage drop include the current draw of the appliance, length and gauge.

The outlet is near the floor and above it at shoulder level, there is a switch for outdoor light and this works. Troubleshooting Guidelines and Examples: What Im confused about (again, my electrical is that of a 1st grader) is the following: Just to clarify here its not 30V as the title of the post shows, but 60V? How to intersect two lines that are not touching. Can anyone offer some suggestions? Your problem is likely between the outlet with 60V L-N and one of the outlets with 0V L-N probably the closest one. Can someone help me try to figure out what is causing these weird readings to happen outta nowhere? How can I figure out why this electrical receptacle is dead? In fact, it's wired exactly the same way as your 15- or 20-amp home outlets are, albeit with heavier 10-gauge wire, instead of 14- or 12-gauge wiring. At these outlets: One small update: I plug a different power strip into the outlet and the voltage measurements are identical as if no power strip is plugged in. If any of the wires look corroded, strip them until you see shiny copper and clean the connections. Find many great new & used options and get the best deals for 20/30/50 Amp Temporary RV Power Outlet Electric Outdoor Housing Box Receptacle at the best online prices at eBay! I checked it out with my multimeter, and I tried it in a different closet. The best way to troubleshoot this type of electrical problem is to locate the upstream outlet that is working and giving normal voltage readings. I tested a switch with a resistive load and saw almost no leakage and it wasnt DC, which is pointing to the DC being caused by the connected load. Thanks for any help you can give. This process of inspection should be made on all of the working outlets and abnormal affected outlets until the problem is discovered. I am not sure of code if a dryer needs it's own 120V run to provide it.

The ground screw is usually located in a metal bar along the right-hand side of the electrical panel. When I test outlets in a room that has no power I put both tester probes in the outlet and I get a reading of 1.7 1.3 volts. While such currents would generally not be large enough to cause a fire unless they were sufficient to trip the breaker on the other side, they could still be lethal to someone touching the "disconnected" circuit. Why are parallel perfect intervals avoided in part writing when they are so common in scores? Turns out that my non-RMS meter will read DC voltage on the AC setting, but only in one direction. One days years ago, an outlet at the end of a run stopped working. I'm a trainee hydraulic engineer in Indonesia. If a circuit is run as two wires from the panel to the load, then when the breaker trips everything in the circuit will be de-energized. Light flashes on then turns off. Under load conditions, there should be some neutral-ground voltage - 2 V or a little bit less is pretty typical. 30 amp, 250 volt, 6-30R, 2-pole, 3-wire. A "live" circuit will carry the 110, an "off" circuit may carry some lower voltage. it may be that you have a faulty switch or an induced voltage that shows you have 50v on the switched live conductor. I went through and carefully flipped each breaker off and on and that did the trick. Precaution: Identify the circuit, turn it OFF and then Tag it with a Note before performing any wiring or inspections. This list of articles will help you learn about the features and benefits provided by GFI and GFCI Receptacles and how they are wired. Unfortunately, if only one breaker trips, devices on the side of the circuit controlled by disconnected breaker may receive a generally-small amount of current through devices connected to the live breaker. I'm making a couple of assumptions here, since you changed out one of the sockets, you understand that the breaker must be turned off in order to work on the circuit and that you are actually using a voltmeter to make sure the circuit is dead when the breaker is off before opening up any outlet box. As mentioned previously, you only need 2 wires for 240V. By the way, the wiring in my house is all aluminum. Why hasn't the Attorney General investigated Justice Thomas? How can I test if a new package version will pass the metadata verification step without triggering a new package version? I know US and UK practice are different here, in the UK we have a rule that a circuit must not be switched on until the resistance of its ground is measured and recorded as satisfactory. Use Raster Layer as a Mask over a polygon in QGIS. Is it a bad ground somewhere perhaps?? Hot-ground reading should be the highest of the three readings. Power at Ceiling fan reading 30 volts instead of 120 volts Hello, My ceiling fan and light have been installed for a couple years and the fan and light both stopped working recently. Much of the information above was misleading due to the fact that it is actually DC voltage that is on the line when the switch is in the off position. This is a typical indication that a splice or connection to the neutral has been lost. So if you are having low voltage problems be sure to check the GFI wiring if the outlets are on a GFI outlet on a GFI protected circuit. Considering it's getting 13v even on going hot to ground, maybe that means the hot wire melted somewhere (?). It only takes a minute to sign up. We checked the outlet with a meter and it reads that it only gets 203volts. Connect and share knowledge within a single location that is structured and easy to search. 30V should, then, be very unlikely in a direct circuit even with poor connections.
