This document discusses the electrical design of a textile mill. It includes specifications for the different electrical systems used, including the types of cables and earthing systems. Load calculations are presented for the existing and proposed distribution systems. Design considerations like voltage drop and cable sizing calculations are also covered. The document aims to ensure the electrical design meets relevant safety standards through proper load assessments, equipment ratings and installation practices.
