hi guys ,
i have to install new 3 phase cable to mushroom sheds and am not full sure off the size of cable i need. i have worked it out that i need 5 by 25mm swa. the cable run is 70 meters long and will be buried in the ground and will be ran with 5 other cables of the same size as there are a total of 6 sheds all in a row( does this mean i have to take grouping factor in to consideration). the loads for each shed is 15 amps lights and sockets, 32 amps for cooler all single phase and there is one 3 phase motor taking a 15kw total load. does my cable size sound right to yous that know more than me,
also the 3 phase motor and cooler will never be on together so could i get away with a smaller cable
thank ypu for any helpfull replies
