First time posting here, and this is gonna be longer than I want, so
thanks in advance for your time.

The lights in one room of my house used to flicker occassionally, which
got to be really annoying, so we called in an electrician. He replaced
the 15A breaker, and it seemed to work OK for a while. About two weeks
later, the problem happened again, and he came back out to replace the
breaker. This particular breaker controls 4 can lights in a room, a
fan, an outside Security light, and the Garage Door Opener.

About 6 months later, the lights in the same room, would just go out.
The Garage door wouldn't open, and the fan wouldn't work. Basically,
there was no power on the circuit, but the Breaker never tripped. If
we Flipped the Breaker off and then back on, everything would work
again, sometimes for days a a time, sometimes for just minutes.

Last week, we called the electrician to come back out, and once again
he replaced the breaker on Thursday. Sunday evening, the lights went
out again, and we couldn't get them to come back on. So, the
electrician came back out today. What we discovered is that the panel
bus where this particular breaker is located has a little burn spot on
it, and the breaker that he replaced on Thursday, also seemed to have a
little debris on the area that connects to the bus.

He made sure that the panel bus was cleaned, and that the new breaker
had no debris, but by the end of the day, the lights in the room went
out again.

This particular room is an addition between the house and what used to
be a detached garage. We are still unsure of exactly how this
particular rooom was wired, but there are 3 separate switches that
control the lights in the room, One switch that controls both the
lights and fan, and another recepticle that has a switch for the fan,
and a dimmer for the lights. The electrician and I were extemely
confused by how this particular room was wired, but he is not sure that
the room is wired with 4 way switches.

The electrical panel for my house is actually in a pantry, and is
extremely inconvenient to get to. My Electrician says that we will now
need to replace the entire panel because the bus appears to be bad. He
gave me a cost estimate of $1400, and said that he can get his guys to
fix the wiring in the addition for $200 more. There is virtually no
attic space above the pantry, as the entrance to the attic is on the
other end of the house. The electrician wants to move the panel to a
location that is more accessbile, so has suggested either outside the
house(not a good option), or pu the panel into the living room which is
not the most appealing, but we can work around it.

None of the other outlets in the room are on this breaker, they
actually come from a second panel in the Garage.

We searched and searched for possible loose wiring, but he is convinced
that the problem lies in the panel bus.

What suggestions do you have, and are the prices that he quoted
reasonable for the work that will need to occur. Also, is this
something that can be done be a novice electrician, or is it imperative
to have a certified electrian put th new box in.

Thanks again for your help.
