Lighting & Power Cable Calculation

This document provides a load distribution schedule for a panel with 36 ways located on the ground floor. It lists the circuit number, load description, quantity, VA rating, wire or cable size, MCB rating, and phase loads for each circuit. The total connected load is 27 kVA and the total demand load is 26 kVA. Circuit loads include lighting, sockets, special units, and exhaust fans. MCBs are to be equipped with 30mA earth leakage protection. A second panel with 12 ways and located on the ground floor is also summarized.
