Breaker faulty so entire box has to be replaced. Amazing how code requires them to replace all breakers, but if that is done then they have to replace the aluminum pole, and install new ground and and and.... so a $2000 cost for box replacement almost triples, all because the breaker isn't made anymore.I am getting other quotes. Typically it costs $800-$1,200 to have a qualified electrician upgrade an existing panel to 100 amps, or $1,500-$2,500 if a new panel is needed. 2  Expect to pay $1,300-$3,000 to upgrade to 200 amps, or $2,000-$4,000 to go to 400 amps.
