how much to install larger electrical panel
Homes may also have sub-panels that are located elsewhere, which are smaller versions of the main panel and wired through it. Typical costs: 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. Expect to pay $1,300-$3,000 to upgrade to 200 amps, or $2,000-$4,000 to go to 400 amps. Installing a new sub-panel runs $500-$1,000.
