Er, the 10kW single-lamp version is listed as "208/480 volt, 3 phase power supplies". There just has to be a 380-415V 'export version' available.

Right now, the homestead has a whopping 125-amp 120/240V service. {The “new and improved” 20,780Y/12,000V utility feed with 3750kVA padmount transformer is due next week.}
