Electrical Wiring Estimating and Costing by Dr. S.L. Uppal and G.C. Garg is a foundational textbook published by Khanna Publishers. It is widely used in diploma and degree courses for electrical engineering to teach the systematic process of planning and budgeting electrical installations. Core Concepts of Estimation
According to the text, estimating is the pre-assessment of materials and costs required to execute a specific job. The process generally involves:
Material Quantities: Predetermining the exact number of wires, cables, switches, and fittings needed.
Cost Analysis: Calculating the total expense by consulting current price catalogues and market surveys.
Labour Estimation: Assessing the number of workmen required based on the complexity and time limit of the project.
Overhead Charges: Including supervision costs, contractor profit, and transportation. Key Topics Covered
The textbook provides detailed guidelines on various installation types:
Residential & Industrial Wiring: Estimates for internal wiring in houses, workshops, and commercial halls.
Service Connections: Procedures for estimating overhead and underground service lines. Key Features
Distribution Systems: Planning for L.T. (Low Tension) distributors, street light feeders, and 11 KV substations.
Safety & Compliance: Integration of Indian Electricity Rules (1956) and BIS codes to ensure reliability and safety.
Technical Design: Practical designs for small transformers, chokes, and bell circuits. Accessing the Material
