When two shore cords are connected to marina outlets of different ratings the total amount of power available is limited to the smallest rating. For example when connected to a 50 amp and a 100 amp outlet since the current in the two cords is equal the maximum current available is 100 amps (50 + 50). However, the SHF converter is unique in that it will divide the current in the cords proportionally so more current is taken from the cord connected to the larger breaker. If used in the previous example the available current is now increased to 150 amps enabling more loads to be used onboard.
