[QUOTE="Hefferl, post: 193358, member: 2471"] My understanding is Volt Drop = (mV x Ib X L) / 1000 So in your case you should be using 4.34A as your design current (Ib) not the tabulated current carrying capacity of the cable. You would then get (44x4.34x40)/1000 = 7.64V For 1.0mm and (29x4.34x40)/1000 = 5.03V for 1.5mm [/QUOTE]
