Wiz kid was not the first to suggest trouble with the Neutral or the Ground
Reread my post which was before his.
When a light bulb explodes it is usually an overvoltage condition that causes it.
Here is what you need to do:
1): Ask the power company to install a Power Line Monitor at the point of entrance.
This will record all Voltage Variations and it will be easy to tell if the problem is
coming from the power network or not.
2): If the line monitor shows clean at that point, the next thing I would check is the
wiring inside the Main Circuit Breaker Panel. You can do most of this yourself, but
be careful. You want to check that all the wire terminals at the Breakers, Neutral Bar
and Ground Bar are Tight ... a loose wire can cause all sorts of trouble. It can also
be a loose Neutral wire at one of the many junction points in the home. You would
need an Electrician to check all of those and also to check that the wires (usually aluminum)
going into the Main Breaker and in the Meter Tray are not corroded and properly tightened.
You can not touch these yourself as the Current at those locations is Very Dangerous.
Let us know how it works out. I am interested in the final outcome.
