My mother's house has seemed to loose half the power upstairs, while the rest of the house is up and running. People have told me it was a breaker, but none of them were switched. Does anyone have any ideas on what the problem is and is an electrician needed for repair.

You did not give any indication of what size house or what the age is, but what you describe could just be one circuit.

Many breakers will trip, but the handle does not move or only slightly moves.

Try moving the handles to the OFF position and then back ON.

If the breaker has trippged then you will fill the difference.

If that does no solve the problem the the mostly likely problem is a bad connection and the most likely place is at a receptacle.

But from the sound of your question you don't have any electrcial experience so I suggest calling an electrican.

Usually in the US you have 2 phases of power coming in at the panel. Although older panels (Circuit breaker box) might be configured differently, You'll usually have every other CB on a phase (i.e. Top left breaker is phase A, second down left breaker is phase B, etc.).

Losing a phase could be a power company problem, a masthead-service entrance problem, a problem behind your meter head, or a problem within your CB box/panel/bus-bar.

You might want to first check with your power company, although an electrician could easily identify this issue as well, and the back-up of his diagnosing that as the problem would help to bring a swifter response/correction from the power company should it be caused from their equipment.

Electricity is an equal opportunity killer, don't work on the electrical system if you aren't qualified to do so. Testing equipment in the hands of the inexperienced, and used incorrectly can lead to injury, property damage, and/or death.

" the US you have 2 phases of power coming in at the panel......"

You have a single phase...two poles.....

"...measure once.....cut twice....throw that one away and cut a new one...."
