how much does a new breaker panel cost
1 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.3  Installing a new sub-panel runs $500-$1,000.et a guy who works for a company and does it on the side too. The total cost for a new panel and breakers is about 300 bucks (depending on how many breakers and what not). I'll gladly pay someone 400 in labor to wire in my panel while its hot and have it done in a few hours.
