120v AC, 220v AC, DC???
The electrical requirement of our tankless heaters are typically 120 volts AC by 5 amps at the maximum.
A dedicated circuit is not required but is recommended for tankless units as a shared circuit might have another device or appliance that could cause electrical interference with the tankless unit.
