question 1 and 2 by showing calculation.
A final circuit feeds a group of 7 numbers switch socket outlets (SSO) at 230.9V. The length of the cable from the protective device to the group of the socket outlets is 20 meters. The circuit is the single core, copper conductor, PVC insulated cable, enclosed in conduit. The expected average connected load of each socket outlet is 500W at 0.85 power factor. Design the installation that satisfies the following requirement 1. The Line Conductor if the permissible voltage drop is less than 2%. 2. Protective devices rating in Amp to satisfy overload protection 3. The minimum size of CPC conductor
