All circuit breakers off but still have power
I have only 1 circuit breaker panel. I was tiling and need to shut off
the power to my counter outlet. I turned off every breaker but still had power. How is this possible? Can a breaker fail and continue to supply power to an outlet when powered off? |

Are you measuring power using a digital meter? -- Joseph Meehan Dia duit |

first try turning off main breaker...........
you need to check if other circuits are powered when you believe they are off |

if you still have power at the outlet even after turning off the main
breaker, have your electrician unplug the power company meter. if you still have power it's coming from the neighbor's house. wrote: I have only 1 circuit breaker panel.

Can a breaker fail and continue to supply power to an outlet when powered off? Is this an apartment or condo? If it is, it could be you are getting power from the neighbors breaker panel. Not uncommon in older apartments. I once worked in an old building with 4 apartments. Talk about a nightmare. Everyone was paying for the neighbors power. I was able to separate all the outlets to the proper meters, but not all the lights. I could have done it, but the cost would have been outrageous for the owner and he told me his price limit and said to do the best I could. Mark |

Can a breaker fail and continue to supply power to an outlet when powered off? The answe is yes cicuit breakers can fail in the on position and though the tripper appears off the contact are still being made. Rule No one. NEVER assume a circuit dead without testing it. And in case your TESTER might be dead, test before turning it off too. That could mean little or no extra work, such as plugging in an outlet tester (and making sure it works), then turn off the breaker and see it go out. -- 93 days until the winter solstice celebration Mark Lloyd http://notstupid.laughingsquid.com "God was invented by man for a reason, that reason is no longer applicable." |

I am in a detached home, not sharing electrical with anyone. I tested
by plugging in a radio and hitting every breaker. The radio never went off. So, lets assume I have a broken breaker. How do I locate the breaker for this circuit or test each breaker to find the broken one. |

How do I locate the breaker for this circuit or test each breaker to find the broken one. Did you try the main breaker? That might be informative. Maybe it's a battery powered radio. Most battery-powered radios I've had anything to do with don't switch over unless the power cord is physically disconnected. You could disconnect each breaker in turn. Or check the voltage across each breaker while they're all off (one will have 0 volts, the others will be 120 v -- unless they're ALL bad). -- 93 days until the winter solstice celebration Mark Lloyd http://notstupid.laughingsquid.com "God was invented by man for a reason, that reason is no longer applicable." |

oups.com... I am in a detached home, not sharing electrical with anyone. I tested by plugging in a radio and hitting every breaker. The radio never went off. So, lets assume I have a broken breaker. How do I locate the breaker for this circuit or test each breaker to find the broken one. (1) leave all circuit breaker off and use a voltmeter (or a light bulb) to probe the output of all breakers. If you find 120V, that's the culprit. (2) first eliminate all the working breakers, then remove the uncertain ones one-at-a-time until you find it. (3) Froogle "circuit breaker locator". |

You are using a radio powered by batteries or by default an electric one that has switched over to batteries when the AC was cut off. ==== |

All circuit breakers off but still have power
I have a strange one Im replacing a lot of switches & outlets down stairs when I cut the power test the outlets and switches all is good however when I was trying to work the up stairs I turned the breaker off and with test plug it into all the outlets tester showed no power so pulled a cover off standard porcelain light to replace it with a switch I test the wires again before starting both the black and white showed red but the flasher was beeping slower than when power was on I decided to check the outlets same thing there. I checked the tester again nothing I put my multimeter on no voltage when I use the power tester all wires show red or hot I have two new testers and checked them both on it and a circuit elsewhere they are working you thing I have another circuit wire in I turned all the circuits off in the rooms around it no difference same problem in my bedroom with bother breaker

Short version breaker off all outlets and switches are off when I open the I used two new meters and both white and black short hot according to the meter but outlet and multimeter showed no power this also happened in another room on another breaker but on the same flloor

No big thing. It is a product of the very high impedance test equipment we are using these days. I have a GFCI that keeps going bad. So this time I put a multimeter to the wires instead of using a voltage tester that just beeps. What I found is the hot (Black) wire from the circuit breaker panel has approximately 12 VAC on it, even when disconnected at both ends. I pulled the wire back and forth in the conduit to try to move it if it was shorted to another wire, but that made no difference. There are 2 other hot wires running through the same conduit. when I shut either one of those off the voltage drops to about 4..5 and when I shut them both off it is zero. I assume this is inductance. Short of running the wire in a separate conduit can I fix this and is it what is causing my GFCI's to fail. |

So this time I put a multimeter to the wires instead of using a voltage tester that just beeps. What I found is the hot (Black) wire from the circuit breaker panel has approximately 12 VAC on it, even when disconnected at both ends. If I get 120 VAC on my multimeter, I trust it. If I get 12 or 37 or anything else weird, I turn the digital off and go get the Simpson. It's not as convenient but the old analog doesn't seem to get fooled by phantom volts the way the digitals do. If the analog shows the same reading, then I've got a wiring problem. I've never actually had that happen though. |

Some new digital VOMs have dual inputs now, high and lower impedance to solve that problem. I think someone reported here that there were adapters, essentially a resistor bridge that you could plug in to older Flukes, etc too. |

Holding one probe in each hand cancelled them out - as it does on a digital meter if it is capacitive or inductive. At 37 volts even if it is NOT phantom - and is real leakage, it is generally not much more than slightly unpleasant - - - |

A resistor across the inputs seems like a better idea. |
