how to choose the cable rating for load (KW)? EXAMPLE.50KW load

Answer Posted / shabeeb

50kw load will take 87 amps (approx.). There is table of
different types of cables available in the manufactures
site. More over there is so many factors are there to
select a cable. Such as the type of material (copper /
aluminium), single core or multicore, how and where the
cable is being laid, the length of cable(for voltage drop
calculation), type of load and its starting current (for
motors), future load etc. Normally if the load is 50KW,
70sq.mm Aluminium cable or 50sq.mm copper cable can be used.
