Hello, im after a bit of advice reguarding the cable to supply a db in a farm shed, the design current is 32a and the run is 61 meters. the vd with 25mm is 3.42 which is going to be ok but i would of liked a little less due lights need to be on 4mm but only by 1v, anyway i rang for a price for 25mm but they havnt got any 2core in till friday so wont give me a price so i ask for a price of 35mm as i was considering this if the cost wasnt ott compared to 25mm so allow for further upgrades, but they didnt have that while friday either, i wanted to get an idea tonight but now everywhere is now closed, i started to think could i just use 16mm 4core and double the wires up the questions are
1. Is 16mm 4core cheaper than 25mm 2 core.
2. Is the vd worked out as normal then just halfed as this better than 25mm or is there a factor to take in account. (e.g 16mm = 5.47/2=2.735 vs 25mm = 3.42)
Thanks
