You can't have 350 kVA capacitor bank; it will be 350
kVAR.. because capacitor banks draw only reactive power..

Minimum IR value of 1.1 kv grade 3.5c (300, 240,185,150,120,95,70,50,35,25) sqmm Aluminium XLPE cable and 4c (16, 10,6 & 4) sqmm cu arm cable between RY,YB,BR,RN,YN,BN,RE,YE,BE & NE.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
