According to NEC Code, reasonable efficiency can be achieved if the total sum of voltage drop of branch circuit plus feeder is within ______ of the rated voltage

For the feeders of voltage level above 600V, the ampacity of supplying both transformers and utilization equipment shall not be less than transformer name plate rating and  _____ of the designed potential of the load of the equipment meant to supply

Which of the following statement is correct:

(1) All feeder conductors using common neutral conductor when installed in metal raceways shall be grouped together:   
(2) The above said grouping is made in order to avoid induction heating of surroundings
