You are given two wattages which correspond to two voltages, which should
also be listed on the same plate. The typical residential electrical service
is 120/240 and will be the higher wattage rating. Apartment buildings and
condos typically use three phase services which supply 120/208 and will be
the lower wattage rating.

Upon closer inspection, you are correct in that the ratings are for
two different voltage setups. Would this wattage necessarily
represent the stove going full blast? i.e. all four burners on full,
and the stove on max?
