Answer / a.yogeswaran

1 hp =750watts
35hpx750=26250
total load P=26.25
current I=26.25X1.74
=45.675(not in market)
=63A
cable size will be as 25cumm2 XLPE/SWA/PVC and 16cumm2 Y/G.CU.PVC.ECC(as required)
Breaker=63A 100mA ELCB Breaker
MDB 01 QUANTITY
Bus Bar Size=20mmx10mm

Answer / waleed hourieh

P=35*746= 26.11 kw
I= 26.11 *1.74*1.25=56.7a
So the CB = 63A.

Materials list :
63A TP MCCB .25KA
63A/100mA ELCB .
60*60 MANHOLE COVER HEAVY-DUTY
35METER UPVC BLACK PIPE HEAVY-DUTY
4C*25MM2+1C*16MM2 Y/G.= 38 METER
63A TPN ISOLATOR
