Electrical Wiring Estimating and Costing: A Comprehensive Guide by S. L. Uppal
Electrical wiring is an essential part of any building construction or renovation project. It involves the installation of electrical cables, switches, outlets, fixtures, and appliances that provide power and lighting to the premises. Electrical wiring also requires careful planning, designing, estimating, and costing to ensure safety, efficiency, and quality.
One of the best books that can help you with electrical wiring estimating and costing is Electrical Wiring - Estimating & Costing by S. L. Uppal and S L. This book was first published in 1986 and has been revised and updated several times since then. It covers all the aspects of electrical wiring, such as:
The principles and methods of electrical wiring
The types and specifications of electrical wires, cables, conduits, accessories, and fittings
The rules and regulations of electrical wiring according to the Indian Electricity Rules and the National Electrical Code
The estimation and costing of electrical wiring for different types of buildings, such as residential, commercial, industrial, institutional, etc.
The preparation of electrical wiring drawings, schedules, bills of quantities, tenders, contracts, and reports
The testing and inspection of electrical wiring installations
The maintenance and troubleshooting of electrical wiring systems
The book is written in a simple and clear language with numerous examples, diagrams, tables, charts, and formulas. It also includes practical exercises and problems at the end of each chapter to test your understanding and skills. The book is suitable for students, teachers, engineers, contractors, electricians, and anyone who is interested in learning about electrical wiring estimating and costing.
If you want to get a copy of this book, you can download it as a PDF file from various online sources[^1^] [^2^] or buy it from Khanna Publishers[^1^]. You can also check out other books by S. L. Uppal and S L on related topics such as electrical engineering materials[^3^], electrical power systems, and electrical machines. These books will help you gain more knowledge and expertise in the field of electrical engineering.
In addition to the book by S. L. Uppal and S L, you can also find some useful tips and tricks for electrical wiring online. Here are some of the best ones we found:
Use the end of a hanger to find a drilling location. Instead of measuring from the foundations to find the location to drill up a wall, you can use an insulation hanger or a coat hanger. Snip off the end at a 45-degree angle and insert it into your drill. Make a small hole at a 45-degree angle on the floor next to the molding. Homeowners will hardly notice the hole because it is so small.
Use a tennis ball to pull cable. When pulling communications wire, tie jet-line to a tennis ball. Throw the ball to the wire's destination. Hook your wire to the string and pull.
Use a hot air gun to aid in bending PVC conduit. A hot air gun comes in handy when you need a quick bend for PVC conduit. Just heat the area until pliable and then make your bend. Larger conduits can bend by inserting the area of the conduit through a 3 or 4 inch PVC tee and the hot air gun in the remaining opening in the tee. Leave the conduit in the tee until it's bendable.
Make large holes without proper drill bits. When you need to make large holes for conduit and you don't have a large drill bit, try this. Make your template where you want to drill and drill a series of holes around the exterior. Follow up with one center hole and be sure you're level. Finish with a piece of 1/2 inch rigid and a hammer to bang out the hole clean.
Keep wires dry using silicon. This idea is useful when you are running underground or working in damp locations. You can take a little silicon and squirt it in the wire nut and this will keep water and moisture out.
Use paper to hold a screw on a screwdriver. Using a piece of paper about 1/2 inch by 1/2 inch, wrap the head of a screwdriver and slip it into the slot on the screw. This will work best when the slot is deep. You may have to bend paper once to tighten the slot. This also works for nut-drivers.
Use a new light bulb to replace an old light bulb. First test to see if the circuit is dead. Clean the broken particles that remain in the socket with a screwdriver or pliers. Then insert the new light bulb into the socket twisting in reverse, as this will remove the broken end of the old light bulb (usually this is the hardest part to take out). This should clean out all damaged parts leaving the socket ready for the new light bulb.
Make sure all wiring connections are tight and have full contact of the conductors being joined. Very loose connections can lead to arcing, in which electricity jumps through the air from one conductor to another, creating tremendous heat. Prevent fire hazards by using approved wire connectors (\\\"wire nuts\\\").
These are just some of the many tips and tricks that can help you with electrical wiring estimating and costing. However, nothing can replace proper training, experience, and safety precautions when working with electricity. Always follow the rules and regulations of electrical wiring according to your local codes and standards. ec8f644aee
