I've had two different systems suffer from problems with the aluminum
entrance cable (the big stuff in the meterbase). One blew the main circuit
breaker whenever the waterheater cycled. Turn out to be a loose connection
at the main breaker - connection got hot - breaker pops. The other was a
corroded connection in the meterbase caused weird voltage issues and random
flickers and such. Cleaned the connection and all was well (added some anti
oxidant compound to keep it from happening again.)

Of course there are several potential issues with code violations and
safety- but lets not get into that :-)
