Fuse Box/Breakers HELP - Circuit not working :(?

we had a similar problem. the first electric outet in the circuit was bad inside and as soon as that was replaced, everything came on when we reset the breaker.

If your "friend the electrician" is actually an electrician, then he would've used a voltmeter to check the breaker and he would have known if the breaker needed to be replaced. Invest in a voltmeter or a real electrician.

Check all the breakers to make sure voltage is leaving the breakers. The make sure all screws on the breakers and the neutrals (white wires) are tight. If the panel check out okay, you have an open circuit. You can test the circuit with a circuit tester and it will tell you whether you have an open hot or neutral; however, it just as easy to pull all of the none working receptacle out and check for loose connections. If you don't don't which breaker energizes that circuit you better turn them all off. Keep in mind that a working receptacle could also have the loose connection; however, unless you know every receptacle on the circuit, it's almost impossible to determine which one are on the circuit. If you do not find it in the "dead" ones, start removing the closest working ones. It could also be in a junction box in the attic, a light box, or a switch box.

If you drove any nails into the wall lately check there.

Sounds like a loose wire in a junction box. Also check the neutral (white)wire in the panel. First of all find a "real" electrician. If the neutral wire connection in the panel is sound, then you have a job on you hands. If the house was always wired to code, then all junctions should be accessible. If this is the case(I doubt it) then you need to trace the wiring from the panel and pull the cover from ALL junction boxes on that circuit. Redo all connections in every junction box on that circuit. More than likely, you will find there have been many hands on your electrical system in the past, and there may be many invisible junctions, that are not only illegal, but very very unsafe as well. If there are hidden junctions, you have a major job on your hand. Junction boxes can be boxes that only have connections in them, or switches and receptacle as well.

Ask your friend the electrician if he has a volt meter. Trouble shoot the circuit to find the problem. Check for an open neutral along with checking the hot wire. Hard to believe you stumped an electrician. Is he a real electrician, or joe handyman the maintenance guy?

Hi liew as there is no visible circuit diagram with this link it is not possible. would suggest some familar electronics circuits in books which describe the 555 timer chip would be an advantage. how ever be careful some only have a 1.5 ma output not the full 15ma output so are easy to destroy. radio shack in the states are bad at selling the low output version and still charging top dollar. this chip will be triggered by an earth on one of it's pins. a book on the subject shouls be available if you look on the internet.

Get a voltmeter and check from the neutral bus to the load side of each breaker, and see if one is open. If you find one thats dead, swap it out.

If all the breakers test good then you may have a loose wire in the panel. Check the load side terminal of every breaker and verify they're tight, and no loose or missing connections.

There may be a recepticle that is bad. If it is, then everything feeding off of it will be dead.

you have a break in a wire some place,you are going to have to track it down.
