Weird Electrical Problem

I have a main power box outside with two 50-amp breakers and one 30-amp breaker.

The 50's are single pole or double pole? Coming into your house is 2 120vac lines and a neutral. It sounds like one of those 120 lines is not getting to your subpanel with the 6 20amp breakers in it. What's on the 50's? Does one of them feed your subpanel with the 6 20s in it? |

Half of the breakers are receiving power, the other half are not. Everything was working fine until yesterday when this problem arised. Do you have a voltmeter and know anything about distribution panel wiring? |

Try resetting ALL breakers if that doesnt fix it call power company one side of their line might be out. That has happened here |

Sounds like an open, with one of the legs of the power company's
power. Also sounds like you have some basic electrical knowledge, but this one is outside your skill set at the moment. -- Christopher A. Young Learn more about Jesus www.lds.org ..

electrician. You're into dangerous territory, working with panel boxes. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Jon" wrote in message ...

The other three are working normally. What is going on? You've lost a leg. There are three wires coming from the light pole: 2 120v legs and a neutral. This is almost always a power company problem - one of the secondary windings in the transformer supplying your house has fried and gone open. |

While I agree with those preaching caution and get help I also feel a person who asks a question deserves and answer. If you will find this text "Finally, pick the breaker" about halfway down this page: http://www.thewoodnerd.com/articles/circuitSizing.html there is a picture of 3 breakers. They are 2 single pole 110V breakers and a double pole 220V breaker (number 3). If you use your test probe from any single screw at the right edge of the breaker to neutral buss you should show 110V. For the 220V breaker to be working properly you would need to get 110V at both of the screws. NOTE: than some one has attached a white wire to one terminal of the breaker in this photo and if they took the time to color code it correctly that does not show in the picture. Quote from the page "Also notice how the DP breaker (#3) has just a single toggle (the switch flipper)? Some DP breakers will actually have two toggles tied together with a metal clip, same effect." It sounds like you have lost one side of one of you 220 volt breakers or if you have 220 at the breaker you have lost a connection between that point and the inside panel. Breakers can and do go bad. Losing half of the load on a 220 can and does happen. -- Colbyt Please come visit http://www.househomerepair.com |

When I had the power turned on in my name, I found that only part of the house had power and the rest didn't. All of the circuit breakers were on, and I tried resetting all of them anyway, but that didn't do anything. I called the power company and when they came back out all they had to do was tighten one of the nuts/connectors in the main panel. I think one side of the feed coming into the main panel had a loose connection. I don't necessarily recommend that you try this, but they do make insulated screwdriver-like nut tightener that I found in the electrical department at Home Depot. I bought one in case I had to retighten any of the connectors, but I never had to use it. So, maybe all you have is a loose connection in the main panel. |

If they will not do it, call an electrician. |

I called the power co. and a tech came and checked it out. The lead where one of the breakers connects is burned and the service panel will have to be replaced. |

But, maybe if you are lucky, an electrician will be able to relocate the bad breaker without having to replace the whole panel. |

Unless the panel is of fairly recent manufacture, though, it may be hard to find the parts. This is not a DIY project for most people Agreed. I've done a *lot* of DIY electrical work, both new and repair, and I found it to be a bit challenging. and you may have a hard time finding an electrician who is will to do the repair.

Jon typed: I have a main power box outside with two 50-amp breakers and one 30-amp breaker. A voltage test shows 120 volts passing through them. Three of my six 20 amp breakers in the inside box are not receiving any voltage. They did not trip, just out of the blue for no apparent reason stopped getting any power through them. The other three are working normally. What is going on? Since you have to ask, and that's the most dangerous place there is to play around power, you should get a pro in to take care of it. You have a breaker problem, loose wires or a break further up the line. |

If you don't plan to repair or replace the panel (or plan to do it 'someday'), please tape a note inside the door that position 'X' should not be used, and why. And if you can find a suitable snap-in blank cover for the position with the damaged lugs, you should fill the hole. Just so the next poor SOB doesn't have to start from scratch, etc. Life is what happens while you are making other plans, and you may not be the next person in that panel. Not everyone will think to look, or be able to recognize, that the lug is damaged. -- aem sends... |
