drain wire

Does anyone build their own power cables? I've been using furutech fps 55 n (10 awg) and 032 with furutech f1 50 male connector and IEC, this is a shielded cable so I unbraid the copper shield and twist it together and connect to the earth ground with ground conductor inside the plug to act as a drain wire, is it best to connect to male end or IEC for analog equipment
