During an electrical storm one half of my house lost electricity while
the other half did not. I contacted our electric company and they said
the problem was "their equipment" which burnt out and affected part of
our "service entry cable." They said it's likely that "part" of our
service entry cable services part of our house and other parts service
the rest.

I have never heard of a partial blackout that affects only some
circuits. Can anyone explain this in more detail?

thanks!

All the residential electrical installations I've seen are a "split
220/240 volt" arrangement: dryer, electric range, central A/C run off
220 or 240 volts; of the 120 volt devices (e.g., lights, regular power
outlets, dishwasher), some will run off one "half" (or "leg") of the
220/240-volt supply, others off the other "half" (or "leg"). Typically,
adjacent breakers in your electrical panel will be on different legs of
the supply.
