Answer Posted / engr.muhammad younas khan
CABLE SIZING FORMULAS:-
1ST STEP CALCULATE THE VOLTAGE DROP (Vd).
(1 ph.) Vd= 2 x I x L x P.F/(K x Area mm2)
(3 ph.) Vd=1.732 x I x L/(KxArea mm2)
where:-
I:- Load current
L:- Length of the conductor.(in meters)
K:- 58 for copper conductor and 36 for aluminum conductor.
2 for single phase and sqrt 3 for three phase.
____________________________________________________________
2nd step.
AREA mm2 = 2 X I X L /(K x Vd) (FOR SINGLE PHASE)
AREA mm2 = 1.732 x I x L/(K x Vd)(for three phase)
