Hello fellow sparks, I have a 400 metre drum of swa xlpe 4 core x 6mm cable I need to install 8 x 230 volt x 45 amp supplies to storage units distance from DB of 40 metres down to 35 metres. I propose to pair up the cores within each cable giving me 8 x runs of 2 core 12mm cable colour sleeved at each end (Blue / Brown) and using the armouring as the earth (CPC). Are there any adverse issues or departures from BS7671 with this procedure. It is purely a minge bag trick to save me buying the correct cable And also utilizing the spare 6mm x 4 core cable Also does anybody know how to calculate the Volt drop No table for 12mm! ( calc for 10mm maybe?) Cheers Foxie1
