After I call the electrician, what will s/he actually do to upgrade
the service in my house to 200A ? Other than change the master
breaker, does anything else happen with the panel, or anything go on
between the house and the pole? Among other things I'm tired of lights
briefly dimming when the furnace or the clothes washer or the
dishwasher or my wife makes demands (oops, did I say that out loud?).
Thanks.

He/she will obtain the permit, Obtain the available fault current figure
for the transformer that serves your home, remove the old service
equipment, install new service equipment (main panel) with a withstand
rating that is suitable for the fault current available, install new
service entry conductors that are sized for the increased capacity,
reconnect and add grounding electrodes as necessary to meet present code
requirements, install a new meter cabinet unless the utility prefers to
do it (pepco, DC for instance), reconnect all of the homes electrical
circuits to the new panel, prepare a list of which breakers serve what
outlets (called a panel schedule), arrange for electrical inspection,
and file paperwork with the power utility if necessary.

The utility will then come out and change out your service drop or
lateral if necessary and make any temporary connections that were made
to your new equipment permanent.
