Principles of Cable Sizing; current carrying capacity, voltage drop, short circuit.
Cables are often the last component considered during system design even if in many situations cables are the true system’s lifeline: if a cable fails, the entire system may stop. Cable reliability is therefore extremely important, then a cable system should be engineered to last the life of the system in the installation environment for the required application. Environments in which cable systems are being used are often challenging, as extreme temperatures, chemicals, abrasion, and extensive flexing. These variables have a direct impact on the materials used for cable insulation and jacketing as well as the construction of the cable. Using a systematic approach will help ensure that designer select the best cable for the required application in the installation environment. This lessons will provide students main guidelines for perform this approach.
This presentation, given by Georgia Power, discusses the importance of grounding and bonding. Real life examples are given and how they were handled as well as safety measures.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

1. Site Electrical Earthing System
Introduction
One of the most misunderstood and confused concept is
difference between Bonding, Grounding and Earthing. Bonding is more
clear word compare to Grounding and Earthing, but there is a micro
difference between Grounding and Earthing.
Bonding is simply the act of joining two electrical conductors
together.
Grounding means connecting the live part (it means the part
which carries current under normal condition) to the earth for example
neutral of power transformer. It is done for the protections of power system
equipment and to provide an effective return path from the machine to the
power source.
Earthing means connecting the dead part (it means the part which
does not carries current under normal condition) to the earth for example
electrical equipment’s frames, enclosures, supports etc.
2. People use an earthing system mainly for these
applications
7. Exothermic Welding for Connections
Provides a Molecular Bond Between Conductors or Rods
Current Carrying Capacity Equal to
that of the Conductor
Permanent - Cannot Loosen or
Corrode to Cause a High-Resistance
Connection
Requires No External Source of
Power or Heat
Can be Visually Checked for Quality
Exothermic Welding Process
Aluminum Reduces Copper Oxide, Forming Super Heated Copper and
Aluminum Oxide (Slag).
