安装分电箱往往比从主电箱拉线更经济。" data-en="The most common additional work in EV charger installations is a panel upgrade. If your panel is an older 100A unit or all breaker slots are full, adding a 40–50A dedicated circuit may not be possible. In that case, we recommend upgrading to a 200A panel first. We offer bundled pricing for panel upgrade + EV charger installation. For clients installing in a garage or basement, adding a sub-panel is often more cost-effective than running cable from the main panel.">
