Hello,

Since about December 2008, there has been intermittent flickering of
lights and very brief electrical outages in this house. It occurs on
several circuits at the same time. I had an electrician tighten up
connections in the circuit breaker box, but he did not remove any and
reinstall any breakers. A corroded and detached ground wire from the
breaker box to a water pipe was discovered and has since been
repaired. There was no sign of "arcing" in the box. All connections
were tight.

Could the problem be in a location in the box that is inaccessible
unless the breakers are removed?

I will have Con Edison (utility company) send a technician to inspect
their electric meter.

There have been problems reported by the utility company that I was
told involves the melting salt used on the roads mixing with snow and
leaking into the manholes, causing corrosion of electrical lines.
Such disruption of the lines should affect many houses on the grid,
not just my own, should it not?

My biggest concern is that the problem will occur during heavy usage
of electricity during this summer when the A/C units are running.
