DCC-9 is the best solution to connect an EV charger to the feeder of a panel in an apartment or condo and in single-family homes where no additional breaker space is available. DCC-9 permits direct utility billing to unit for all electricity consumed by charging.

DCC-10 is the ideal solution to connect an EV charger to a new branch-circuit of a panel when breaker spaces are available. DCC-10 avoids the need for major infrastructure upgrades and allows for a simplified EV charging installation.

DCC-12 is the ideal solution to connect an EV charger to a new branch-circuit of a panel when breaker spaces are available. DCC-12 avoids the need for major infrastructure upgrades and allows for a simplified EV charging installation. Unlike the DCC-9 and DCC-10, there is no circuit breaker inside the DCC-12 acting as the intermediary between the VE charger and the electrical panel.
