v1.4.5

Cable Sizer & Voltage Drop

Four modes: Size Circuit (pick the cable from the design current, installation method, grouping, ambient and insulation), Check Circuit (verify a cable someone else chose), Quick VD, and Network — a full radial distribution network that sizes every feeder, allocates voltage drop cumulatively, cascades prospective fault current, and checks the protective conductor adiabatically at the far end. Regional authority requirements enter as editable limit profiles — a rule that cannot be met fails loudly instead of being silently exceeded.
